Office Web Apps will provide web-based versions for desktop versions of Word, Excel, PowerPoint, and even OneNote. Of course, storing and sharing Office documents on the Web is not a new thing. Previously, Microsoft's Office Live Workspace was able to save and manage documents online. However, Office Web Apps provide an advantage by allowing you to actually create and edit documents through a browser. Ultimately, Office Web Apps will inevitably replace Office Live Workspace.
Compared to the full set of functions provided in the desktop version, the editing commands in Web Apps only provide the most basic functions. However, these basic functions can help users more easily update documents and collaborate on the same documents.
Users can save their documents through the Windows Live SkyDrive service (Microsoft's free online storage area), and SkyDrive is completely an online storage site. SkyDrive can provide up to 250GB of free space, making it an ideal storage location for large files and documents that require online access but do not require synchronization. Enterprises using SharePoint can create repositories for these documents to store them internally on their SharePoint servers. Finally, companies using specific Microsoft online services such as SharePoint Online can store documents in the cloud.
Office Web Apps is currently a beta version. Before using Web Apps, you need to first install Office 2010 Beta. After installing Office 2010, you can start Word, Excel, or PowerPoint to try out Office Web Apps.
Take Word as an example. First, create or open a document in Word, and then click on the 'File' menu to access the Backstage. When using Office 2010 for the first time, you can quickly save and open documents and run other commonly used commands through Backstage. From the Backstage, click the 'Share' command, and then click 'Save to SkyDrive'. The system will prompt you to log in to SkyDrive using a Windows Live account.
Four default folders will be displayed - 'Photos',' Videos', 'Documents', and' Public Folder '. The first three folders store items for personal viewing only, while the 'public folder' contains files that you want to share with others. Double click on one of the folders, such as' Documents'. A common "Save As" dialog box will pop up, where you can choose the name and file format of the document, and then save it.
After saving the document to SkyDrive for the first time, you must log in directly to your SkyDrive account through your browser to accept the Web Apps usage agreement. In SkyDrive, select the 'Documents' folder, then select the document you just saved, and then click the' View 'command. A protocol will be displayed, and the document can only pop up in your browser after you accept it. After accepting the agreement, you can save and open online documents more smoothly.
After establishing a workspace through SkyDrive, you don't need to install Office 2010 locally to access documents. Through a browser, you can create, edit, view, delete, copy, move, rename, and download documents.
You can share documents with others through Web Apps, requiring you to send links to your documents to everyone via email. Users with Windows Live accounts and access rights can view and edit these shared documents online.
Web Apps can only run in environments with Internet Explorer 7 and 8 installed; Firefox 3.5 or higher is required to be installed on Windows, Linux, and Mac; Safari 4.0 or higher is also required to be installed on the Mac.

The embryonic form of foreign IPTV business can be traced back to 1985. At that time, several telecommunications companies in the United States (GTE, Ameritech, and Bell Atlantic) conducted experiments on video transmission over fiber optic and DSL. However, due to the fact that the services provided by these companies were not significantly different from those of cable television companies, the video services of telecommunications companies did not become mainstream.
The real starting point for the development of IPTV business should be the IPTV business launched by Video Networks in the UK in 1999. Afterwards, many foreign telecom operators have successively entered the IPTV market. The main driving factors are technological progress and the expansion of market demand: (1) the advancement of IPTV's key technology - video compression technology, which enables video programs to achieve higher picture quality with lower bitstreams; (2) The development of global broadband networks has provided a reliable and stable path for the transmission of IPTV services; (3) The rapid development of broadband access in the world has solved the last mile bottleneck problem in IPTV service provision; (4) Telecom operators have been vigorously developing broadband, but have not received sufficient profits from it, and the profitability of broadband is still limited to the collection of access fees; (5) The opening up of the telecommunications market has led to an increasing number of new entrants entering the telecommunications market through the relaxation of regulatory policies, especially cable television operators entering the telecommunications market, providing users with "triple play" services with existing television services and new telecommunications services. This measure has created a strong sense of crisis for telecommunications operators, who urgently need to find innovative services to improve ARPU and enhance user stickiness; (6) The prosperity of broadband access has not brought prosperity in content services, and most of the business and applications on broadband networks are still in the narrow band period, and the consumption needs of broadband users are far from being met.
Overview of IPTV Market Development
The operators deploying IPTV services are mainly concentrated in Europe, America, and some countries and regions in the Asia Pacific region. Telecom operators usually use high-speed DSL or FTTP technology to provide IPTV services to users. By the end of 2004, the two largest operators with the highest number of IPTV users were FastWeb in Italy and PCCW in Hong Kong, China.
1. North America
In the North American IPTV market, traditional Canadian telecommunications companies are at the forefront. Manitoba Telecom (MTS) and SaskTel have already opened IPTV services using VDSL and ADSL, and Telus and Canadian Bell also plan to enter this market in 2005.
From the perspective of user development, as of September 2004, the number of IPTV users of Canadian telecommunications operators was approximately 50000, accounting for about 2% of the total number of television users in Canada. It is expected that by the end of 2006, the number of IPTV users will reach 250000, with a user market share of 17%, and its market share will steadily increase.
Compared with the Canadian IPTV market, the development process of the US IPTV market is relatively stable. In 2001, Qwest Communications took the lead in launching an IPTV service based on VDSL technology to users in the Phoenix region. Afterwards, numerous independent local operators in the United States actively carried out IPTV services on DSL networks and fiber optic networks within their service areas. Since 2005, the three major RBOCs in the United States - SBC, Southern Bell, and Verizon - have also started deploying IPTV services.
2. Europe
Many telecom operators in Europe also have a positive attitude towards IPTV business, especially FastWeb's success in IPTV business in Italy, which has changed the wait-and-see attitude of many operators. Almost all traditional European telecommunications operators have conducted IPTV experiments, with France Telecom being the most proactive and having already opened services in Lyon.
Belgium Telecom, Netherlands Telecom, Austria Telecom, and Norway Telecom are all conducting commercial experiments on IPTV.
3. Asia Pacific region
The development of broadband has greatly promoted the deployment of IPTV in the Asia Pacific region, and many telecom operators have entered the IPTV market. These telecom operators usually use DSL or fiber optic access technology to provide users with high-speed data, VoIP, and video services including digital television and video on demand. The better performing operators are PCCW in Hong Kong, China and Yahoo in Japan! BB。
Since early 2003, Yahoo! Since the opening of BB's multi-channel radio, television, and video on demand services in Tokyo, Yahoo! BB's television business is gradually integrating with its existing telephone and broadband services, which has driven the rapid growth of TVover DSL users.
PCCW in Hong Kong, China launched a DSL based digital television service in September 2003, with 367000 signed users by November 2004.
Business and Tariffs
The IPTV service not only expands the use of telecommunications terminals, but also expands the range of services that television terminals can support, covering a very wide range of services. IPTV can provide services mainly including television services, communications services and various value-added service. Specifically, television services refer to services related to television business, such as broadcasting and television, on-demand television, personal video recording, etc; Communication services mainly refer to voice services based on IP, instant messaging services, television short messages, etc; Value-added service refers to TV shopping, interactive advertising, online games, etc.
When foreign telecom operators enter the IPTV market, their preferred services are often television and VOD services. Some operators also provide a variety of value-added service, such as Canada's MTS, which provides interactive program navigation and call display that can be searched by topic or title, and has opened a TV portal, through which users can learn weather and other public information as well as channel information; FastWeb in Italy has opened the PVR (Personal Video Recording) service, which allows users to control live television through STB operations; Some operators also offer applications such as television commerce.
Foreign telecom operators mainly consider market affordability and investment in deploying IPTV services when pricing IPTV services. Due to the degree of market competition in their respective countries and regions, as well as the differences in network investment and operating costs among telecom operators, there are significant differences in IPTV service fees among them. The basic cost of IPTV services for Video Network in the UK is $65 per month (including 1Mbps broadband access), while for Yahoo in Japan! BB is $19 per month.
The difference in business fees also reflects the competitive strategy of operators when entering the IPTV market. Generally speaking, in countries with a high degree of market openness, in order to establish a competitive advantage against cable TV operators who have already entered the telecommunications market, maintain the loyalty of existing telecom business users, and reduce user disconnection rates, telecom operators often lower the pricing of IPTV services compared to existing market competitors when deploying IPTV services, and provide users with multiple business bundles to achieve greater discounts for users; In order to win users from competitors or cultivate users' habits of using pay TV, telecom operators often launch IPTV services at low prices. In the fiercely competitive pay-TV market in the UK, the IPTV service fee is generally between $20/month and $30/month, while in some European countries that are not yet accustomed to paying for television, the IPTV service of telecom operators is relatively low, such as Neuf IPTV service fee in France, which is less than $10/month.
Operation mode
In North America and some European countries with high levels of market competition, the government has gradually relaxed regulations on the mutual entry of cable television and telecommunications operations, allowing them to penetrate each other, providing opportunities for cable television operators to enter the telecommunications industry.
In response to the competitive situation where cable TV operators provide users with a fusion of cable TV services, broadband access, and telephone services, many telecom operators in Europe and America have also begun to deploy video services mainly focused on television. They have also launched a triple play business model that integrates IPTV, broadband access, and telephone services in the telecommunications field, in order to maintain a more favorable position in the new form of competition.
Therefore, foreign telecom operators often carry out IPTV services in a triple play mode. The Triple play model reflects the close connection between operators and users, and operators can provide users with three types of services simultaneously; Users can use services through the same terminal or different terminals in the home network.
Triple play brings discounts on pricing to users. The bundled services of MTS TV and DSL provided by MTS in Canada have a 12.5% reduction in fees compared to the sum of the two business fees. The Triple play model has greatly promoted the development of IPTV, while also bringing sustained growth in ARPU to operators. About 60% of residential users of SureWest, a small independent telecommunications company in California, USA, have ordered triple play.

The European region is the earliest, relatively fast and mature region for IPTV business development. A detailed analysis of the IPTV business carried out by telecom operators in various European countries reveals that although they consider IPTV business as a new revenue increasing channel, they have their own strengths in the specific deployment and promotion process when launching television business based on the national conditions and characteristics of each country. The various forms of business structure design, flexible and variable tariff standards, and a wide range of content provision all provide a good reference and reference for telecom operators to carry out IPTV business.
Years and major operators of IPTV market entry in some European countries and regions

IPTV is a business that utilizes broadband networks to provide users with interactive multimedia services, with its main characteristics being interactivity and real-time. Through IPTV services, users can receive high-quality digital media services and freely choose video programs on broadband IP networks, achieving substantial interaction between media providers and media consumers.
IPTV can provide services mainly including television services, communications services and various value-added service. Specifically, television services refer to services related to television business, such as broadcast television, on-demand television, personal video recording, etc; Communication services mainly refer to voice services based on IP, instant messaging services, television short messages, etc; Value-added service refers to TV shopping, interactive advertising, online games, etc.
IPTV integrates the relevant characteristics of traditional television and the Internet, so it can be seen as a combination of traditional television services and emerging telecommunications services. The IPTV service not only expands the use of terminals for telecommunications services, but also expands the range of services that television terminals can support. For traditional television operators, the emergence and development of IPTV is a huge challenge, while for telecommunications operators, deploying IPTV services to provide users with new applications and rich services will be an effective way to enhance competitiveness and profitability.
The main driving force for telecom operators to develop IPTV
The development of IPTV by telecom operators can not only promote the development of broadband access, but also increase revenue while reducing user disconnection rates. At the same time, it can also address the challenges from cable TV operators.
The development of broadband access requires strong support from businesses, and the existing narrowband services are far from meeting the needs of the broadband era. Exploring new ways of user growth and business volume growth has become an important issue that fixed network operators need to pay attention to when developing broadband access. Telecom operators urgently need to find new services that can attract users and consume bandwidth, and IPTV is the business that suits this demand.
The development of IPTV business can bring potential lucrative profits to operators. Due to the relative saturation of traditional voice services and the lack of sufficient attractiveness of simple data services, telecom operators urgently need to find new profit growth points. For operators, despite the rapid development of data services and the fact that the network traffic of data services has begun to exceed traditional voice, the ARPU crisis faced by telecom operators cannot be solved due to the low unit price of services and slow revenue growth. Telecom operators provide bundled services including video, which can increase per user revenue while cultivating user loyalty, which is beneficial for maintaining users and reducing offline rates. Research has shown that providing three types of business bundling can reduce the offline rate by 50% compared to only providing a single business, and by 25% compared to providing two business bundling.
In some countries and regions with high levels of market openness, governments have relaxed regulations on the entry of cable television into telecommunications operations, allowing them to penetrate each other, providing opportunities for cable television operators to enter the telecommunications industry. In this competitive situation, telecommunications companies are not willing to fall behind. In order to seize the opportunity in future competition, European and American telecommunications operating companies have begun to deploy video services mainly based on IPTV. Deploying triple play services bundled with IPTV services can enable telecom operators to establish a favorable competitive position against cable TV operators, cultivate market and user demand through IPTV and other video services, and increase their experience in video business operations.
Analysis of IPTV Service Market for Foreign Telecom Operators
Since Video Networks launched its IPTV service in 1999, many foreign telecom operators have entered the IPTV market one after another. From the perspective of global development, although telecom operators believe that IPTV is suitable for future development needs and have begun to deploy this business, due to the lack of sufficient operational experience in IPTV by telecom operators, the operating market is not yet mature, and the user market still needs to be cultivated. This business form is also subject to competition from traditional cable TV and satellite live TV, Therefore, overall, the development of IPTV is still in its infancy.
The operators deploying IPTV services are concentrated in Europe, America, and some countries and regions in the Asia Pacific region. Telecom operators typically use high-speed DSL or FTTP technology to provide IPTV services to users. By the end of 2004, the two largest operators with the highest number of IPTV users were FastWeb in Italy and PCCW in Hong Kong, China. These two companies had nearly 70% of the user market share in terms of television users.
In the IPTV market of North American telecommunications operators, traditional Canadian telecommunications companies are at the forefront. Manitoba Telecom (MTS) and SaskTel have already opened IPTV services in VDSL and ADSL networks, and Telus and Bell Canada also plan to enter this market in 2005. From the perspective of user development, as of September 2004, the number of IPTV users of Canadian telecommunications operators was about 50000, accounting for about 2% of the total number of television users. It is expected to reach 250000 users by the end of 2006, and their market share will steadily increase, accounting for 17%.
Compared with the Canadian IPTV market, the development process of the US IPTV market is relatively stable. Large American telecommunications companies SBC and Quest initially chose to collaborate with satellite television companies to provide IPTV services in the form of reselling satellite broadcast television services. Numerous independent local operators in the United States are also actively conducting IPTV services on DSL and fiber optic networks in their territories.
Many telecom operators in Europe also have a positive attitude towards IPTV business, especially FastWeb's success in IPTV business in Italy, which has changed the wait-and-see attitude of many operators. France Telecom has the most positive attitude and has already opened its business in Lyon, with plans to open its business in Paris in March 2005. Belgium Telecom, Netherlands Telecom, Austria Telecom, and Norway Telecom are all conducting commercial experiments on IPTV.
When foreign telecom operators enter the IPTV market, their preferred services are often live TV and on-demand TV. Some operators also provide a variety of value-added service. For example, Canada's MTS provides interactive program navigation and call display that can be searched by topic or title, and has opened a TV portal, through which users can get public information such as weather and channel information; TCC, a subsidiary of SK in South Korea, provides applications such as time-shifted television and television commerce.
Foreign operators often adopt a bundled service model when conducting IPTV business, which provides users with a triple service - triple play. This is a service model that integrates voice, high-speed internet access, and IPTV. This emerging service model reflects the close connection between operators and users, and operators can provide users with three types of services simultaneously; Users can use services through the same terminal or different terminals in the home network. Triple play is born in a new market environment, which can not only meet the needs of users for dialogue audio services, but also meet their needs for high-end business. More importantly, users can enjoy the tariff discounts brought by business bundling. The bundled services of MTS TV and DSL provided by MTS in Canada have a 12.5% reduction in fees compared to the sum of the two business fees. The Triple play model has greatly promoted the development of IPTV, while also bringing sustained growth in ARPU to operators. For example, about 60% of residential users of SureWest, a small independent telecommunications company in California, have ordered triple play, and the company's average monthly ARPU in 2003 reached around $103, with a user churn rate of only 2%.
Challenges for Operators Deploying IPTV
IPTV has begun to take off globally, and its development has been driven by both technological progress and market demand. Firstly, one of the key technologies of IPTV - the advancement of video compression technology, enables video programs to achieve higher picture quality with lower bitstreams; Secondly, the development of broadband networks by operators has provided a reliable and stable pathway for the transmission of IPTV services; Thirdly, telecom operators have vigorously deployed broadband access, but have not received sufficient profits from it, and the profitability of broadband is still limited to the collection of access fees; Finally, the prosperity of broadband access has not brought prosperity in content services. Most of the business and applications on broadband networks are still in the narrowband era, and the consumption needs of broadband users are far from being met. The above points indicate that the internal technical factors and external demand factors for the development of the IPTV market have basically matured.
However, for operators, deploying IPTV services involves many issues, such as the funding required for upgrading and renovating existing networks, the selection of operational and profit models when launching new businesses, and the competition faced by existing service providers when entering new fields. Overall, the determination of business models, the presence of market competition, and the lack of video content are the main challenges faced by telecom operators when deploying personal video services mainly focused on digital television.
(1) It is unclear whether triple play, which integrates IPTV, high-speed data, and voice services, can reverse the trend of declining revenue for telecom operators. Although some companies have achieved success in using triple play in IPTV operations, the suitability of the triple play business model remains to be verified due to the complex industrial environment in which IPTV operates.
(2) Telecom operators are facing a complex market environment. Compared to cable and satellite television companies, as new entrants, telecom operators have limited market space and limited business price space in the initial stage. In Manitoba, Canada, Shaw Company launched the cable plus TV business as early as 1999, with a bundled service price of CAD 89.95 per month, which is CAD 20 higher than the bundled price of MTS's DSL plus TV launched four years later.
(3) The lack of content is also one of the challenges faced by telecom operators, especially in countries with low market openness, which is particularly prominent. Due to the lack of control over program sources by telecom operators, obtaining content that can attract users is also one of the key issues that operators need to solve when deploying IPTV.
(4) Due to the fact that foreign operators who have entered the television market only conduct business locally and on a small scale, with a small number of users, there are no examples of providing IPTV applications to large-scale users on the telecommunications broadband network. This is also a problem that operators should carefully consider. The bandwidth requirements of IPTV services far exceed those of existing voice and data services, and there are strict requirements for other indicators such as channel switching delay and QoS. How to ensure that users can watch programs of comparable quality to the current cable television network is an important issue that operators need to solve.
Telecom operators face many risks and challenges when entering the IPTV market. How to respond to and mitigate risks is an important guarantee for operators to achieve success in the IPTV field. Drawing on the operational experience of foreign operators, the following countermeasures can be summarized: first, conduct research on the market environment, including national regulatory policies, market size, user needs, user cultural habits, potential profits, etc., and comprehensively analyze these research information. At the same time, analyze competitors to develop a timetable and operational model for deploying IPTV; Secondly, unify the planning of business and network, which includes two aspects: business definition and pricing. The rationality of business planning directly affects the number of users and overall income. Network planning should be combined with business planning and carried out uniformly. Due to the high bandwidth requirements of video services, operators should first consider upgrading the network to support the implementation of multiple business combinations after planning their business; Finally, operators should seek cooperation with content providers and establish a reasonable cooperation model.
The Future Development of IPTV
IPTV business closely connects communication oriented and content oriented businesses, and the combination of these two types of businesses requires deep cooperation between two independent markets - the telecommunications market and the media market. Only with rich content and strong network support can IPTV business achieve rapid development. Since 2004, dozens of telecom operators worldwide have entered the IPTV market, and by the end of 2004, the global number of IPTV users had exceeded 1 million. In the next two to three years, IPTV business will enter a stage of scale development, and the number of users will continue to grow. According to In Stat/MDR company predictions, by 2008, telecom operators' IPTV services will cover over 75 million households worldwide, with actual global users reaching 14 million.
In the early stages of IPTV development, the IPTV business provided by operators mainly focused on live television, on-demand television and other television services. With the growth of the IPTV market, the applications provided by operators will become more diverse. Users can access value-added services such as TV shopping and games, as well as communication services such as voice, instant messaging, and TV SMS through TV.

Microsoft has released the latest internal preview build update for Windows 10 (Insider Preview Build 21337).
The announcement introduced many new features, such as support for reordering and customizing virtual desktops, support for automatic HDR preview on the PC side, and update of File Explorer layout.
In addition to the new features mentioned above, I believe that the following new change is more popular among developers - Windows Terminal will become a built-in application pre installed on Windows 10, becoming a very user-friendly application like 'Notepad'. After all, if you need to use Windows Terminal now, you need to install it from the Microsoft Store or download it from the GitHub release page. In contrast, for users, built-in is undoubtedly more convenient.
After becoming a built-in application, updates to Windows Terminal continue to be made through the Microsoft Store. This change is currently only available in the internal preview version, and we need to wait for it to be officially used.
Windows Terminal is a brand new, popular, and powerful command-line terminal tool. It contains many features that are highly sought after by the community, such as multi tab support, rich text, multilingual support, configurability, themes and styles, support for emoji and GPU based text rendering, and so on. At the same time, the terminal still meets our goals and requirements to ensure that it remains fast, efficient, and does not consume a large amount of memory and power.

The use of the telnet command on the Windows 10 operating system can be roughly divided into two parts:
Part 1: Configure telnet
Part 2: Entering the Black Window
Finally, let's debug and try connecting to the server.
Part 1:
Firstly, configure telnet through the control panel
Open: Control Panel - Programs - Start or Close Windows Functions - Check Telnet Client
Part 2:
Keyboard key operation: window+r - enter cmd enter - enter the original black window - enter telnet enter - enter quit to exit telnet mode
Debugging section:
Thinking organization:
1. The telnet on the window side has been opened
2. The ping command check shows that the network condition is unobstructed
3. And there's something I don't know about

In the words of an industry insider, the spelling of 'telephone' for companies here in the future should be 'television'. This indicates a trend: future telephone companies are transitioning towards television. So, what is the actual development of IPTV?
IPTV has become a fashionable term nowadays, at least in the telecommunications industry, it has become a word that is almost used every day and is increasingly being discussed by people. At the Telecom NEXT conference held in the United States in late March, most of the presentation was about how phone companies deliver video programs. In the words of an industry insider, the spelling of 'telephone' for companies here in the future should be 'television'. This indicates a trend: future telephone companies are transitioning towards television. So, what is the actual development of IPTV?
Firstly, consumers do not know what IPTV is.
A recent survey shows that nearly half of American and European consumers do not know what IPTV is. According to a survey of 6000 users in the United States and Europe (including Spain, the United Kingdom, Italy, France, and Germany) conducted by Accenture, a leading management consulting firm, 46% of users are unclear about what these letters IPTV refer to. In Italy, even 4% of respondents believe that IPTV is a new television competition program.
People in the telecommunications industry are enthusiastic about using technical terminology in their marketing, but the survey results above indicate that this approach is not suitable for IPTV. What telecom companies should do is focus on selling the concept of IPTV: it can enhance the experience of ordinary viewers watching TV, and it is expected to provide more advanced interactive services in the future, which requires a process of market cultivation.
Secondly, there is no mature charging model yet.
Price is a major obstacle to IPTV. In the survey conducted by Accenture, 54% of respondents stated that they are unwilling to pay additional fees for an entertainment service that allows them to search for TV, radio, and music programs at any time.
The IPTV revenue and expenditure model is based on many assumptions, but these assumptions assume a well known and stable market, while at the same time, the core definition of IPTV is in flux.
The behavior and traffic patterns of users will guide the development of the industry. The most important part is to distinguish between online traffic and offline traffic. The biggest concern of network owners is that they only provide a network that others can use for free without receiving any benefits from traffic. So, they must distinguish between online services and offline services. Layered services will protect the interests of both network owners and users.
Once again, telephone companies still face legal obstacles in terms of television services.
In the United States, wired services need to be provided under the policy supervision of county and city governments. For telephone companies, negotiating with the government at the local level is time-consuming. Verizon once mentioned that even if it receives a local license one day, it still takes several years to provide video services to all its users.
The new laws in Texas and Indiana allow telephone companies to obtain licenses from the state government without the need for local authorization, thus greatly simplifying the already lengthy process. Virginia has passed a similar law, but it has not yet taken effect. Currently, IPTV is actually guided by smaller companies, many of which serve rural areas. In addition to obtaining some concessions, their systems are smaller, making it easier for them to adopt new technologies. For large telephone companies, the franchise war is harsh, as they have to deal with thousands of local governments.
Finally, the biggest challenge is that the entire IPTV industry may underestimate what it should do to deliver services, as user experience rather than technology is the most critical factor for IPTV. Although IPTV has some technical advantages, it remains to be proven whether these advantages can win and retain users. Meanwhile, some analysts believe that IPTV does not really need a technological advantage to compete with cable companies. For consumers, convenience is a temptation. Being able to obtain wired telephone services, wireless telephone services, broadband internet services, and television services from a company, also known as "quadruple playback," has great appeal to consumers. The survey shows that users have a clear interest in the types of services that IPTV can provide. For example, in the United States, 37% of respondents choose to be able to watch programs anytime when it comes to how to better watch TV. Moreover, 30% of respondents in Europe stated that they need more movie channels, which IPTV can provide technically.
However, from the above content, it can also be seen that many IPTV implementations are involved in old paradigms such as telephone services, television, video on demand, and so on. After all, IPTV is only an improvement, not a true innovation. When the market changes and remains stuck in the old paradigm, perhaps one day, operators will have to significantly lower prices to retain users. Therefore, in order to win in long-term competition, telephone companies should make certain changes in direction and develop more other service content. Moreover, it should be a revolutionary business with true innovation and an order of magnitude of improvement. And this is something that IPTV operators have not truly solved.

Docker for Windows is a Docker Community Edition (CE) application. The Docker for Windows installation package includes everything necessary to run Docker on a Windows system. This topic introduces pre installation considerations and how to download and install Docker for Windows.
What to know before installation
If your system does not meet the requirements for running Docker for Windows, you can install the Docker Toolbox, which uses Oracle Virtual Box instead of Hyper-V.
Docker Toolbox and Docker Machine users must read: Docker for Windows requires running Microsoft Hyper-V. If necessary, the Docker for Windows installation program will enable Hyper-V for you and restart your computer. After enabling Hyper-V, VirtualBox will no longer function, but any VirtualBox VM images will be preserved. The VirtualBox VM created using docker machine (including the default virtual machine typically created during toolbox installation) will no longer start. These virtual machines cannot be used in parallel with Docker for Windows. However, you can still use docker machine to manage remote VMs.
Virtualization must be enabled. Typically, virtualization is enabled by default. (Please note that this is different from enabling Hyper-V.).
The current version of Docker for Windows runs on 64 bit Windows 10 Pro, Enterprise and Education (1607 Anniversary Edition, Build 14393 or higher). In the future, we will support more versions of Windows 10.
Containers and images created using Docker for Windows are shared among all user accounts on the installed machine. This is because all Windows accounts will use the same virtual machine to build and run the container. In the future, Docker for Windows will better isolate user content.
Nested virtualization scenarios, such as running Docker for Windows on VMWare or Parallels instances, may work, but cannot be guaranteed (i.e. not officially supported).
Docker for Windows installation includes: providing Docker Engine, Docker CLI client, Docker Composite, Docker Machine, and Kitematic.
Installing Docker for Windows
1. Double click Docker for Windows Installer.exe to run the installation program.
If you have not yet downloaded the installation program (Docker for Windows Installer. exe), you can obtain it from download.docker.com..
2. Follow the installation wizard to accept the license, authorize the installation program, and then continue with the installation.
You will be required to use the system password to authorize Docker.app during the installation process. Requires privileged access to install network components, link to Docker applications, and manage Hyper-V virtual machines.
3. Click Finish on the installation completion dialog box to launch Docker.
Starting Docker for Windows
Docker cannot start automatically. To click Start, search for Docker, select the application in the search results, and then click it (or press Return).
When the whale in the status bar remains stable, Docker can run normally and be accessed from any terminal window.
If the whale is hidden in the Notification area, click the up arrow on the taskbar to display.
If you have just installed the application, you can also receive a pop-up success message, provide subsequent steps, and provide a link to this document.
After initialization, select 'About Docker' from the notification area icon to verify if you have the latest version.
congratulations! You are running Docker for Windows.

Definition of IPTV
What is IPTV? This is a fundamental issue.
Before the introduction of the definition of IPTV by the International Telecommunication Union, different standardization organizations and related enterprises had various interpretations of IPTV, and in China, IPTV was also translated into various forms - interactive television, online television, interactive television
At the same time, different industries, operators, and equipment manufacturers have different opinions on what IPTV can do. Although the prospects of IPTV have been described as a huge cake, how to slice the cake has become the focus of industry attention, and all parties are doing their best to seize the opportunity in this huge market.
In fact, due to unclear policies leading to unclear industrial models, behind the popularity of China's IPTV industry, more people are cautiously watching; The limitations of bandwidth and content, as well as the barriers to unified terminal standards, have led to the inability to promote IPTV on a large scale, many experiences cannot be summarized, manufacturers are at a loss, and marketing has also fallen into the awkward situation of thunder, rain, and little. Therefore, the introduction of IPTV international standards will to some extent change the awkward situation of unclear identity, uncertain standards, and feudal separatism.
In the IPTV standards published by the International Telecommunication Union, the definition of IPTV is as follows:
IPTV is a multimedia service, such as television, video, audio, text, images, data, etc., and has certain QoS/QoE, security IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to support the required level of QoS/QoE, security, interactivity, and reliability.
From the definition of IPTV by the International Telecommunication Union, we can see that it mainly includes the following meanings:
IPTV is a multimedia service, and services such as television, video, audio, text, image, and data are all manifestations of IPTV;
IPTV is carried on a manageable IP network and has corresponding level requirements for security, reliability, interactivity, and service quality.
IPTV is not so much a business as a service. Although it may seem like a different translation of a word, it means looking at IPTV from different perspectives, and "business" is more from within the operator, which is the business project used by the operator to earn profits; However, "service" is defined from the perspective of customers, that is, IPTV can meet the needs of different categories of customers. Therefore, the author prefers to interpret IPTV as a service to customers rather than an internal business of the operator.
Through this definition, we can find that concepts such as online television and interactive television are only a description of IPTV's image and cannot fully cover the meaning of IPTV. However, this definition still has certain positive significance for promoting IPTV and promoting its development in China.
IPTV service requirements
In the IPTV standard, the service requirements of IPTV are subdivided and listed according to service direction, function, etc. Some are required, some are recommended, and some are optional. This is actually a law that has been explored based on summarizing the development experience of IPTV around the world.
In the early stages of IPTV development, people wanted to incorporate all the functions that the Internet could provide, not only to achieve video on demand, video live streaming, online browsing, but also to achieve applications such as videophone or conference television, pursuing "large and comprehensive". However, this is not realistic, as the result often makes the devices and systems too complex and the network overwhelmed. Therefore, it is not only necessary but also necessary to classify IPTV services appropriately.
In short, IPTV is a new industry formed by the intersection of multiple traditional industries, including operators, equipment manufacturers, content providers, terminal manufacturers, and other links. The coordination and integration of the industry chain is the determining factor for its market success; The value chain of IPTV is more complex, involving multiple types of enterprises such as set-top boxes, CDNs, DRMs, middleware, audio and video codecs, etc. The complexity of the IPTV system and architecture can be seen from its standard documentation.

According to predictions from globally renowned data analysis and consulting firm GlobalData, the total revenue of Singapore's pay TV market will decline at a compound annual growth rate (CAGR) of 1.4% from 2020 to 2025 due to a decrease in IPTV subscription volume.
The latest "Singapore Telecom Operator National Intelligence Report" released by GlobalData shows that due to increasing consumer demand for OTT video platforms, the number of IPTV subscribers in the country will decline at a compound annual growth rate of 2% in the forecast period from 2020 to 2025. The penetration rate of pay TV households will also decrease from 39.3% in 2020 to 33.8% by the end of 2025.
Deepa Dhingra, an analyst in the telecommunications industry at GlobalData, said: "After users of Starthub (Singapore Telecom) have fully transitioned from cable TV to IPTV services, Starthub will become an IPTV dedicated platform in Singapore to provide pay TV services by 2025. During this period, SingTel (Singapore Telecom) The company will lead the local pay TV market by offering independent pay TV packages through promotional discounts, and has developed multiple bundled sales plans aimed at attracting new subscribers. SingTel has been offering discounts of up to 50% for various IPTV packages and offering free subscription services for up to three months, including multicast services bundled with fiber optic internet and pay TV services.

According to the pay TV forecast update report from the analysis company Digital TV Research, the number of IPTV users will surpass that of cable TV by 2026. Between 2021 and 2026, IPTV will increase by 63 million users, bringing the total number to 398 million.
The main reason for this situation is that the huge shift from cable television to IPTV in China will continue, "explained Simon Murray, chief analyst of digital television research.
By 2026, China will have 226 million IPTV users, while the rest of the world only has 172 million left. Between 2021 and 2026, China will add 19 million IPTV users. However, by the end of 2026 during the same period, China will lose 39 million cable TV users, bringing the total number to 89 million.
Digital TV Research predicts that between 2021 and 2026, pay TV users will increase by 13 million, bringing the global total to 1.01 billion. China will continue to provide nearly one-third of the world's pay TV users, expected to reach 315 million by the end of 2026. India will account for 178 million. By 2026, China and India will jointly account for half of the global pay TV users.

When we talk about online streaming and OTT, we come across many terms, among which IPTV is one of them. We are undergoing a transition from traditional broadcasting modes such as cable or satellite television to streaming based on the Internet, and IPTV as a system will play an important role in this transitional stage.
Basically, customers are not as concerned about owning content as they are about accessing it. This is where IPTV appeared. Let's carefully study the exact meaning of IPTV, its working mode and architecture, the types of IPTV services, and the future of IPTV. So, what is IPTV?
IPTV refers to protocol television based on the Internet, where the Internet is used to provide live or on-demand television programs and videos. IPTV is a system in which digital television services are transmitted to subscribers through broadband or Internet connected media through Internet protocol technology. It is slightly different from the digital videos accessed by millions of users on websites or applications such as YouTube or Netflix, but it has ubiquitous universality. Unlike standard cable or satellite connections, in IPTV, multiple televisions can use a single subscription in a single home.
IPTV brings more advantages and convenience to viewers, allowing them to choose the programs they want to watch anytime, anywhere, without having to watch any live TV programs currently playing. To understand how IPTV differs from traditional television, let's compare traditional television viewing methods with IPTV - both cable and satellite can work by allowing users to "tune" to specific channels within the signal, while the fundamental difference is that the cable is connected through cable while the satellite is wireless (until it reaches your house). The main example of cable TV is Time Warner cable, which is transmitted through coaxial cable connections, while the example of satellite TV comes from providers like DirecTV, which is transmitted and transmitted to the audience through radio waves.
IPTV uses an Internet Protocol (IP) based network to transmit TV channels to users' set-top boxes. Unlike cable and Satellite Network, the Internet provides content by providing the same client server model that presents e-mail, websites, and other Internet based services. As we will further mention in this blog, IP or Internet protocol is a language used to transmit data packets between computers connected to the Internet network.
Consumers request and receive TV programs, and video content is transmitted to viewers through an Internet Protocol (IP) based network (rather than cable or satellite). IPTV does not transmit content in real-time like cables or satellites, but forgets the model through transmission. IPTV can store programs on servers at the transmission end, allowing users to request content anytime through the Internet.
Compared to traditional channel surfing, IPTV is very similar to browsing the internet. It only uses IP (Internet Protocol), which is a transmission mechanism used to transmit videos to viewers. When viewers click on any TV program or request a video, videos from different sources (servers) will be divided into packets and sent over the Internet. The video server transmits the program to an existing home through an internet connection through a fiber optic cable, sends a request, and puts the program back in.
In the past few years, IPTV has been continuously growing. The total number of global IPTV users has now exceeded the 130 million mark. As of the end of 2015, there was a net increase of 6 million subscribers in the past 24 months. On this basis, many young people will tailor their home IPTV usage to OTT services.

Plex is a very user-friendly home media management system that can make your cold movie and television folders very beautiful, and can be seamlessly used on multiple platforms. It is the preferred software for home NAS media management. But plex has a very powerful feature that is not well-known to everyone, which is its Live TV&DVR function. With this feature, you can turn your plex server into a multi-functional iptv server and record the programs you want to watch on any device at any time. With it, you can basically bid farewell to your set-top box. You may want to watch a variety show on Mango TV, but it happens to be busy at that time. You can record the program in the background by using plex's schedule in advance, and then watch the video when you have time. Of course, this feature is currently only available to plex pass members. If you are not a member, you can use IPTV to watch live TV, but there is no scheduled recording function.
1、 Download xteve
Plex's Live TV&DVR function originally meant to be able to tune digital TV signals, requiring hardware support. However, for ease of use, someone has developed an xteve to simulate digital TV tuners. As long as you have a streaming source for TV live streaming, you can use Plex to watch live broadcasts.
Select the version to download according to the system.
The downloaded compressed file only has one xteve service program file. Once opened, you can enable xteve settings.
2、 Prepare a live streaming source for m3u
There are many live streaming sources that can be found online, and the most stable method is to use the live streaming sources of your own broadband operator's set-top box. These sources are not encrypted, and as long as you grab the link to the live streaming source, you can use them stably for a long time. First, search online to see if other netizens have captured the corresponding live streaming sources of the operator in their province. If so, you can use them directly. If you can't find it, you can also try to find a crawling method online.
Simply put, my gripping method. I am using a mobile set-top box that allows me to watch live broadcasts as long as I am connected to a wireless network. Therefore, the idea I use to capture is to connect the set-top box to a hotspot that is opened by a laptop. This way, all connections to the set-top box will be made through the laptop's wireless network card. Then, I use the packet capturing tool Wireshark to capture network packets from the wireless network card, and use the remote control to replace all stations in the set-top box. Finally, I analyze the links to the HTTP protocol in the network packet, You can find the live streaming addresses of various TV stations. Just save these addresses in the format of the m3u source file in the m3u file.
Mobile live streaming address
This is some of the live stream links I captured. After capturing the stream, first open it on the computer using a vlc player to test if it is usable. If it is, it can also be used on plex.
After having the source, it is necessary to configure the station logo and program table information for the TV source http://epg.51zmt.top:8000/ This great god's website can obtain program schedule information and automatically generate m3u files with platform logos after uploading their own m3u files. You can also modify the logo file yourself, and the link after the logo in the m3u file is the logo image address.
3、 Configuration of xteve
Open the xteve. exe service and enter http://your IP: 34400/web/in the browser to enter the configuration side of xteve.
Set xteve configuration
There are two options for the source of EPG, which is actually the information source of the program schedule. If you choose PMS, plex will directly retrieve program information from your network source, http://epg.51zmt.top:8000/e.xml This address is a domestic program schedule path. If you choose the PMS option, plex will not be able to capture the logo image, and there will be a situation where plex's app cannot find which station is which. But this method is simple to configure, just set the m3u address in xteve and fill in the program source path in plex. Why is there no logo? The general logo is saved in an M3U file, but when reading the logo, plex does not directly read it in the M3U file, but in the XML file of the program source. The program source above only has program information and no logo information, so plex cannot generate an icon. If XEPG is used as an option, it is generated by the xteve software through network EPG information to generate a local new XML file. By setting it to include the program's logo information, plex obtains the logo and program table information. The following will focus on the configuration method of the xepg option. Many friends choose the xepg option and plex cannot search for channels because of configuration issues.
Decoder Settings
Settings for stream decoder
Because the default setting is the first option, the video is directly read from the original stream without passing through other software. However, due to various reasons such as the stream protocol, plex may experience tuning failure and cannot play. Many people encounter situations where plex can be found but cannot be released, because the first option is chosen here. The three items below are decoding streams using xteve, ffmpeg, and vlc. I chose vlc decoding and filled in the path address of vlc.exe in the VLC/CVLC Binary Path below. This way, the plex stream is the stream decoded by vlc, and as long as vlc can play plex, it can be played.
Fill in the path of the vlc player
After configuring the basic options, you need to configure the path of m3u in the playlist option.
Type selection m3u
Fill in the m3u file path
After joining, you can see the number of TV stations in the live stream source.
Next, set the source of the program list in the XML TV option
The final step is to associate the TV station with the program list in mapping, and only by setting plex correctly can programs be searched.
Open a TV station in mapping.
Name all TV stations according to this rule.
Some TV stations do not have corresponding TV station information in their program schedules, and each program schedule information cannot be duplicated. These TV stations can use virtual program schedules that select xteved.
Virtual Program List
After configuring all the TV stations, the settings for xteve are complete.
Set up the completed xteve interface
4、 Dvr settings for plex
Select Live TV&DVR in the plex settings and click on Set plex dvr. Manually enter the network address.
Click on 'Connect' to continue.
The searched channels will be displayed here. Click to continue
Choose to have an xmltv guide on your server
Fill in the XML file path
Continue all the way to the end, wait for plex to read the program list information, and then you can see the TV programs in the Live TV&DVR options on plex's homepage.
Plex Live Program
Just click on it to watch the live broadcast.
If you want to record that program, you can directly click on the small dot of the program to make an appointment for recording.
Record the program you want to watch regularly
I have created a new movie media library called Recorded TV Programs. Advanced options allow you to set information such as the quality of recorded videos.
Android app interface
Summary: The above is the method of using plex pass members and xteve to watch IPTV live streaming on the Windows platform. The setup process is relatively complex, but it is very convenient to use, and the timed recording function is very practical. Many people encounter situations during the configuration process where there is no platform logo, plex cannot read channels, or channels can be read but cannot be played. This article can be referred to for solutions. The versions on other platforms should be similar and have similar solutions.

Definition of IPTV
What is IPTV? This is a fundamental issue.
Before the introduction of the definition of IPTV by the International Telecommunication Union, different standardization organizations and related enterprises had various interpretations of IPTV, and in China, IPTV was also translated into various forms - interactive television, online television, interactive television
At the same time, different industries, operators, and equipment manufacturers have different opinions on what IPTV can do. Although the prospects of IPTV have been described as a huge cake, how to slice the cake has become the focus of industry attention, and all parties are doing their best to seize the opportunity in this huge market.
In fact, due to unclear policies leading to unclear industrial models, behind the popularity of China's IPTV industry, more people are cautiously watching; The limitations of bandwidth and content, as well as the barriers to unified terminal standards, have led to the inability to promote IPTV on a large scale, many experiences cannot be summarized, manufacturers are at a loss, and marketing has also fallen into the awkward situation of thunder, rain, and little. Therefore, the introduction of IPTV international standards will to some extent change the awkward situation of unclear identity, uncertain standards, and feudal separatism.
In the IPTV standards published by the International Telecommunication Union, the definition of IPTV is as follows:
IPTV is a multimedia service, such as television, video, audio, text, images, data, etc., and has certain QoS/QoE, security IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to support the required level of QoS/QoE, security, interactivity, and reliability.
From the definition of IPTV by the International Telecommunication Union, we can see that it mainly includes the following meanings:
IPTV is a multimedia service, and services such as television, video, audio, text, image, and data are all manifestations of IPTV;
IPTV is carried on a manageable IP network and has corresponding level requirements for security, reliability, interactivity, and service quality.
IPTV is not so much a business as a service. Although it may seem like a different translation of a word, it means looking at IPTV from different perspectives, and "business" is more from within the operator, which is the business project used by the operator to earn profits; However, "service" is defined from the perspective of customers, that is, IPTV can meet the needs of different categories of customers. Therefore, the author prefers to interpret IPTV as a service to customers rather than an internal business of the operator.
Through this definition, we can find that concepts such as online television and interactive television are only a description of IPTV's image and cannot fully cover the meaning of IPTV. However, this definition still has certain positive significance for promoting IPTV and promoting its development in China.
IPTV service requirements
In the IPTV standard, the service requirements of IPTV are subdivided and listed according to service direction, function, etc. Some are required, some are recommended, and some are optional. This is actually a law that has been explored based on summarizing the development experience of IPTV around the world.
In the early stages of IPTV development, people wanted to incorporate all the functions that the Internet could provide, not only to achieve video on demand, video live streaming, online browsing, but also to achieve applications such as videophone or conference television, pursuing "large and comprehensive". However, this is not realistic, as the result often makes the devices and systems too complex and the network overwhelmed. Therefore, it is not only necessary but also necessary to classify IPTV services appropriately.
In short, IPTV is a new industry formed by the intersection of multiple traditional industries, including operators, equipment manufacturers, content providers, terminal manufacturers, and other links. The coordination and integration of the industry chain is the determining factor for its market success; The value chain of IPTV is more complex, involving multiple types of enterprises such as set-top boxes, CDNs, DRMs, middleware, audio and video codecs, etc. The complexity of the IPTV system and architecture can be seen from its standard documentation.

When we talk about online streaming and OTT, we come across many terms, among which IPTV is one of them. We are undergoing a transition from traditional broadcasting modes such as cable or satellite television to streaming based on the Internet, and IPTV as a system will play an important role in this transitional stage.
Basically, customers are not as concerned about owning content as they are about accessing it. This is where IPTV appeared. Let's carefully study the exact meaning of IPTV, its working mode and architecture, the types of IPTV services, and the future of IPTV. So, what is IPTV?
IPTV refers to protocol television based on the Internet, where the Internet is used to provide live or on-demand television programs and videos. IPTV is a system in which digital television services are transmitted to subscribers through broadband or Internet connected media through Internet protocol technology. It is slightly different from the digital videos accessed by millions of users on websites or applications such as YouTube or Netflix, but it has ubiquitous universality. Unlike standard cable or satellite connections, in IPTV, multiple televisions can use a single subscription in a single home.
IPTV brings more advantages and convenience to viewers, allowing them to choose the programs they want to watch anytime, anywhere, without having to watch any live TV programs currently playing. To understand how IPTV differs from traditional television, let's compare traditional television viewing methods with IPTV - both cable and satellite can work by allowing users to "tune" to specific channels within the signal, while the fundamental difference is that the cable is connected through cable while the satellite is wireless (until it reaches your house). The main example of cable TV is Time Warner cable, which is transmitted through coaxial cable connections, while the example of satellite TV comes from providers like DirecTV, which is transmitted and transmitted to the audience through radio waves.
IPTV uses an Internet Protocol (IP) based network to transmit TV channels to users' set-top boxes. Unlike cable and Satellite Network, the Internet provides content by providing the same client server model that presents e-mail, websites, and other Internet based services. As we will further mention in this blog, IP or Internet protocol is a language used to transmit data packets between computers connected to the Internet network.
Consumers request and receive TV programs, and video content is transmitted to viewers through an Internet Protocol (IP) based network (rather than cable or satellite). IPTV does not transmit content in real-time like cables or satellites, but forgets the model through transmission. IPTV can store programs on servers at the transmission end, allowing users to request content anytime through the Internet.
Compared to traditional channel surfing, IPTV is very similar to browsing the internet. It only uses IP (Internet Protocol), which is a transmission mechanism used to transmit videos to viewers. When viewers click on any TV program or request a video, videos from different sources (servers) will be divided into packets and sent over the Internet. The video server transmits the program to an existing home through an internet connection through a fiber optic cable, sends a request, and puts the program back in.
In the past few years, IPTV has been continuously growing. The total number of global IPTV users has now exceeded the 130 million mark. As of the end of 2015, there was a net increase of 6 million subscribers in the past 24 months. On this basis, many young people will tailor their home IPTV usage to OTT services.

WPS supports iOS, Android, Windows, Mac, Linux operating systems, as well as online web collaboration documents. Microsoft's Office platform is the same as WPS, except that it cannot run natively on the Linux operating system.
4. Different software volume sizes
The WPS installation package is relatively small, and the desktop typically only takes up hundreds of MB of hard disk space, resulting in faster startup. MS Office, on the other hand, has a larger volume and requires a longer installation time, typically occupying several GB of space.
5. Different software functions and performance
WPS software has a better localization experience for Chinese users, with more user-friendly functions and interface operations. It provides many convenient and fast operations and template materials, but there are slight performance disadvantages, such as opening thousands of rows of Excel table data, which may cause some lag. Although Office requires a certain learning curve, its functionality and performance are more powerful, and it can load documents with large amounts of data at a faster speed.
6. Different pricing models for fees
WPS adopts a free value-added pricing model, and the vast majority of features can be used for free for life. The membership version charges 89 yuan per year, while the super membership version charges 179 yuan per year. Microsoft Office adopts a trial or buyout system. The Office 365 personal version costs 398 yuan per year, while the home version costs 498 yuan per year and can be used by 1 to 6 people. The Office 2021 one-time buyout costs 1998 yuan.
7. File cloud storage space is different
The free version of WPS provides 1GB of cloud storage space, the member version has 100GB of cloud storage, and the super member version has 365GB of cloud storage. For Microsoft Office, free users have 5GB of OneDrive cloud storage space, and paid individual users have 1TB of cloud storage space.
8. Different software compatibility
As early as 1996, Microsoft proposed to collaborate with Kingsoft to share WPS Office format with Microsoft Office format in order to enter the Chinese market, making the two compatible. Later on, with the popularity of the Windows system, more and more users turned to Office software. Microsoft Office was no longer compatible with WPS document formats, while WPS had to be overturned to fully compatible with Office software formats.

Top Five Features of Office 2021 Update
Dynamic array in Excel (one formula returns multiple cells)
XLOOKUP in Excel is more powerful and easier to write than VLOOKUP
Inventory images built into PowerPoint (and other applications)
Simultaneously editing Excel, PowerPoint, and Word desktop applications
Translation tools for emails, phrases, and almost everything
All Microsoft Office apps
You will notice the rounded edges, performance updates, and other small user interface changes on the ribbon tab (such as the undo/redo button being moved, the search bar being updated, and text, commands, documents, help, etc. can now be found). Microsoft documentation has made some updates to all applications here, but this list is more complete:
Hide Quick Access Toolbar: Your Quick Access toolbar may disappear by default, but you can restore it by right-clicking the ribbon and selecting Show it. Then, when you right-click the toolbar, you can choose to display the command label.
Collaborate with Excel, PowerPoint, and Word
Co author: Documents saved on OneDrive or SharePoint can now be edited by multiple people using desktop applications in Word, Excel, or PowerPoint, and you will see icons of each person's photo currently in the file. In addition to co creation, some enhanced features have also been introduced
Auto save: stored on OneDrive or SharePoint, you will be able to turn on/off auto save
Modern comments: Insert>comments and start a thread that may reply or @ mention colleagues. You can open the comment pane from the top right corner. The function previously known as' comments' in Excel has been renamed to 'comments' and can still be used from the' review 'tab.
Accessibility Checker: Review>Inspection Accessibility Now suggest how to improve the document.
Translation: Use 'Review'>'Translation' on phrases or entire documents/worksheets/slides
Excel Overview
A Microsoft blog about the new features of Excel 2021 is available for reading, but our list is more complete (for example, with Power Query functionality). The image shows the new features in this version and the features you may have missed from the past 10 years:
Unhide multiple worksheets: right-click on the worksheet → Unhide and then select multiple worksheets
LET: Simplify long formulas by assigning names to certain parts and then referencing them, usually referred to as variables in programming. Rewrite=IF (C6 * 1.05<200200+C6, C6 * 1.05) with=LET (FiveP, C6 * 1.05, IF (FiveP>200, FiveP, 200+C6)), where FiveP is the given and reused name.
Workbook Statistics: This review tab feature displays an overview of your worksheet and workbook. Identifying the last cell with data is also useful, as it can lead to particularly large file sizes.
Worksheet view: One person's filters may interfere with others' processes during simultaneous editing, so you can now filter or sort only for yourself, and you can also save the filter/sort view and reuse it.
XLOOKUP for Excel
XLOOKUP: VLOOKUP (the third most commonly used function in Excel) is now largely considered a legacy function and will continue to exist simply because most Excel users regretfully do not explore new features. Merging two tables by looking up values in another table is useful in many cases. VLOOKUP has always been necessary, but it is not convenient. Experts have always turned to the extremely complex INDEX MATCH combination. XLOOKUP not only fixes most of VLOOKUP's defects, but also more intuitively writes and understands for beginners while doing so.
The required syntax is XLOOKUP (lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode]). Input 1-3 is required, I sometimes use 4 but rarely use 5-6. The following are its inherent VLOOKUP issues:
a) Default exact match (the most common use case).
b) Find from right to left or left to right because you specified columns instead of table arrays
c) Inserting columns in the lookup table will not cause problems.
d) XLOOKUP also replaces HLOOKUP as it applies to arrays (one column or one row)
e) If not found, returns the selected value with the fourth input.
Benefits of being more ambiguous based on the last two inputs
f) By approximate matching of the next maximum or next minimum item.
g) Search in reverse order.
XLOOKUP is not perfect as it still cannot handle duplicates in lookup tables or merge columns for lookup, but Power Query's merge queries can fill these gaps.
For bidirectional lookups using INDEX MATCH MATCH combinations, XMATCH (lookup_value, lookup_array, [match_mode], [search_mode]) is also useful.
Excel's dynamic array
A formula returns an output on a cell, which is how Excel has been working until now
Premise of dynamic array: a formula can now return multiple cells, replacing the overly complex concept of "array formula". Now you can execute=A3: A15 * B3: B15 in C3 instead of using=A3 * B3 and drag down to C15, and the results will be displayed in cells C3: C15:
You may see # SPILL! If the data is already in cell C4: C15, or if the dynamic array is set to return a value in an Excel table (although the table can be used as an input source), an error will occur.
#Reference: A5 # refers to a dynamic array starting from A5 (which can be a dynamic number of multiple rows or columns).
TRANSPOSE: Although this is not a new function, it is now easier to flip rows and columns linked to the source array.
ANYTHINGIFS: Nest an IF in TEXTJOIN to concatenate text according to standards, copy MEDIANIFS, STDEVIFS, or any similar method you prefer.
Six new functions have been released with dynamic array:
UNIQUE:=UNIQUE (Column) returns a unique value, and there are more advanced multi column options. The generated dynamic array grows or shrinks according to the source data.
SORT: I often use=SORT (UNIQUE (Array)) to create a sorted data validation list.
SORTBY: Use SORT to sort by the first column, otherwise I recommend SORTBY. Using SORTBY, you can refer to the columns to sort compared to SORT's column index numbers (which may be out of range).
FILTER: Generate a filtered output array for certain columns.
SEQUENCE: Generate a continuous number of specified array sizes, and set the start and step sizes. Use cases include TOP5 sales or all sales in the past 7 days.
RANDARRAY: Generate a random number matrix, specifying the required columns, rows, minimum and maximum values, as well as whether they must be integer values.
Power Query in Excel
Extract from PDF: Data>Get Data>From PDF, and even merge multiple PDFs into one folder
Fuzzy matching: Match Fred, Freddy, or Elizabeth with Lizzie or 078-524 with+4478542. When merging queries, check this option to match tight but imprecise text, specify ignoring case or spaces, match must be tight from 0 to 1 (default is 0.8), and the maximum number of matches is or matches with completely different conversion tables (such as UK to UK).
M IntelliSense: Obtain autocomplete functionality when writing custom M code in custom columns, advanced editors, or formula bars, such as in Excel, double-click or press Tab to lock suggestions
Input data: Add custom data directly in Power Query from this homepage tab function
Column analysis: A colored bar appears below the column name, displaying errors, null values, and values, but the view tab has new options.
By default, the first 1000 rows are displayed as all rows in the bottom left corner of the screen.
PowerPoint
The new features of PPT 2021 can be found on the Microsoft blog, but our list is more complete.
In addition to the first three, these features are also available in Excel, Word, and Outlook, but are most commonly used in PowerPoint
Slide link: If the document is saved in the cloud, you will get this option when you right-click on the slide
Reading order: Select how screen readers prioritize objects from "Review">"Check accessibility"
Enhanced recording: Slide Show>Recording now supports your videos, laser pens, and ink
Image transparency: configured through "Image Format">"Transparency"
Sketch lines: The new line format option means that the lines around the shape can now have curves that mimic hand drawn shapes
Hexadecimal code coloring: Set the color by clicking on 'More Colors', where you can change the color to type in hexadecimal or RGB codes
Auto Play Gif: Insert any Gif and automatically play, or click | | to pause
Ink update: Drawing>Ink can replay animations of previously created hand drawn ink, and also provides rulers, erasers, and lasso selectors (not in Outlook). By default, the drawing tab may not be open and can be enabled through File>Options>Customize Ribbon
Built in inventory image library
The 1000 types of inventory content in 6 categories are mainly used for PowerPoint, but can also be used for Excel, Word, and Outlook. More content is added every month, but non advanced subscribers can only access a portion of the library.
Inventory photos: Pixel perfect high-definition photos from Insert>Pictures>Inventory images, some with many blank spaces for eye-catching full screen slide backgrounds
More icons: Insert>Icons are now part of the library and larger
Cute character: Microsoft hires models to pose in different positions with transparent backgrounds
Sticker: Telegram/Snapchat generation will prefer these characters over cutting them out
Video: A subtle video that automatically plays without sound, looping through once completed, perfect for eye-catching title slides, only available in PowerPoint
Word
Word and Outlook have relatively few features besides the ones mentioned above
Dark mode: Click File>Account and select Black to obtain the true dark mode, with white text on the black canvas
Line Focus: View>Immersive Reader has a new 'Line Focus' view
Outlook
Translation function: Translate messages by right-clicking on the translation phrase or setting automatic translation from File>Options
Inking: The drawing tab in emails allows you to annotate emails or draw on a separate canvas. The drawing tab may not be open by default and can be enabled through File>Options>Customize Ribbon
With the help of dynamic array, XLOOKUP, Stock content and other updates, the Office 2021 upgrade may really change the rules of the game.

What's New in Office 2021
Improved operation interface: Office 2021 has made significant improvements to the operation interface, removing the 3D ribbon image at the beginning of opening Office2021 files and adding a large single image. The improvement of Office 2021 has only done some superficial work. The 'File Tab' has taken on a completely new look, making it more efficient for users to operate. For example, when a user wants to create a new document, they can see preview images of many available templates.
Full editing of PDF documents: PDF documents are really a headache, and it is said that they are headache because they have many inconveniences to use in work. Even if users want to extract some formatted or unformatted text from PDF documents, it is maddening. However, with the new version of the Office 2021 suite, this issue will no longer be an issue. Word in the suite can open PDF files and users can edit them as they please. You can save the modified results in PDF files or in any file type supported by Word.
Automatically create bookmarks: This is a new feature in Office 2021, which will undoubtedly improve the efficiency of those who work with large Word documents. Users can directly navigate to the previous work or browsing page without dragging the 'scroll bar'.
Built in image search function: It is not easy to search for images on the internet and insert them into PowerPoint presentations. Microsoft has also taken into account users' needs in this regard, and users can use Bing Search to find suitable images in Office 2021 and then insert them into any Office document.
Excel Quick Analysis Tool: For most users, using good methods to analyze and present data has always been a headache. With the Excel quick analysis tool in Office 2021, this issue has become much simpler. After users input data, Excel will provide some suggestions to better format, analyze, and present the data, and so on. Even some experienced Excel users will love this feature very much.

Microsoft just shipped a brand new cumulative update for Windows 10 devices, this time as a preview in front of the next Patch Tuesday rollout due in March.

The brand new update is KB5022906, and it is targeted at the latest versions of Windows 10 still receiving support, namely Windows 10 version 20h2, version 21H2, and version 22H2.

Microsoft reveals in the changelog that Windows Spotlight is getting further improvements around the lock screen, with links now opening faster when clicked.

The next changes are members of update KB5022906:

This update improves your experience if you use Windows Spotlight on your lock screen. The informational links open faster.
This update addresses an element that affects IE mode. The text around the status bar is not always visible.
This update addresses accessibility issues. They affect Narrator around the Settings webpage.
This update addresses an issue that stops hyperlinks from employed in Microsoft Excel.
This update addresses an issue that affects a particular streaming app. The issue stops video playback after an advert plays within the app.

With regards to known issues, Microsoft disapproves new bugs are included. However, the update ships with the same old glitch that impacts Microsoft Edge, with the legacy version of the browser removed although not automatically replaced by the brand new Chromium-powered browser.

Windows 10 will continue to get support until October 2025, as Microsoft is otherwise fully committed to increasing the experience with Windows 11. The discharge of Windows 11 came with upgraded system requirements, so some Windows 10 devices weren't permitted to move to the new operating-system.

As such, when the 2025 deadline is reached, Windows 10 could be pulled, with devices running it without other option rather than be replaced with hardware entitled to the switch to Windows 11.

In 2021 when Microsoft announced Windows 11, one of the biggest changes the new operating-system included did not concern the new features however the computers where it had been supposed to be installed.

Windows 11 was therefore offered with upgraded system requirements, essentially abandoning lots of devices which, at least initially, seemed perfectly able to running the OS.

Leaving aside the controversy produced by this approach, Windows 11 was therefore blocked on lots of computers.

The upgrade mysteriously turned up on unsupported devices this past year, despite Microsoft clearly proclaiming that computers not meeting the machine requirements would stick to Windows 10 until 2025 when the support comes to an end.

And earlier this week, everything happened again, with Microsoft once more providing the upgrade to Windows 11 to unsupported devices because of what Microsoft describes being an accident.

Inside a post around the Windows Health Dashboard, Microsoft says that the computers offered the upgrade weren't allowed to complete installing Windows 11 anyway. The issue has already been resolved, the company claims.

"Some hardware ineligible Windows 10 and Windows 11, version 21H2 devices were offered an inaccurate upgrade to Windows 11. These ineligible devices didn't meet the minimum requirements to operate Windows 11. Devices that experienced this issue were not able to to accomplish the upgrade installation process. This issue was detected on February 23, 2023, and resolved on the same day," Microsoft explains.

The organization still recommends users to stay with Windows 10 if their devices don't meet the system requirements to run Windows 11. Windows 10 will receive updates until 2025, at which point this OS version is going to be retired. Upgrading the hardware will become the only option, as otherwise, no further security updates could be available.

The release of the Windows 11 Moment 2 update witnesses a brand new improvement visiting the Start menu.

As most users have no doubt about, the debut of Windows 11 brought us a significant Start menu makeover. Now centered alongside all of those other taskbar icons, the beginning menu no more uses the live tiles that were available in Windows 10, but a more static design borrowed from Windows 10X.

Since the first form of Windows 11 rolled out, the beginning menu continues to be constantly getting further refinements. And the Moment 2 update continues this trend with goodies targeted at business users.

Devices running Windows 11 Pro will begin displaying recommendations and suggestions regarding files along with other content within the Start menu.

AI for the win

Microsoft says the whole experience is powered by AI, and also the purpose would be to make it easier for users to find the content they need in a easier and straightforward way.

"For those of you who use Windows in business setting, we're assisting you get to what you need more quickly and easily?awhether that be considered a file you'll need in an instant, or your cloud PC so that you can work the way you want," Microsoft says.

"Available on Windows 11 Pro devices and higher which are Azure Active Directory (AAD) joined, we're personalizing your experience by delivering AI-powered recommended content in your Start menu. Simply click to open the Start menu and discover related happy to assist you to get ready for upcoming meetings, quickly access files you're collaborating on, and more."

Moment 2 is now available for users who manually look for updates in Windows 11, however in business environments, the rollout is controlled by system administrators.

Microsoft has detailed the company's latest method to improve the delivery of Windows updates, especially in the case of companies where deploying urgent patches is important.

Available for devices enrolled in the Windows Update for Business deployment service (in Intune and Windows Update for Business), this program is mainly targeted at resolving zero-day security vulnerabilities in a timelier manner.

Microsoft says a great way is to configure the number of days necessary for a reboot to 1 or 2 days, as it prevents forced reboots to minimize the disruption within the organization.

Full focus on security updates

At the same time, additionally, it provides a reasonable window to deploy security updates, though when zero-days are now being involved, immediate rebooting might be required.

"If you are using the expedite capability the very first time, then just before reaching a zero-day vulnerability scenario, identify in case your devices are eligible to receive expedited updates or not. If your devices are current and active, perform a test run and expedite these to an older security update," Microsoft explains.

"For example, in case your devices possess the August security update, then you could test the expedite capability by utilizing target release as June. The Summary and Device reports in Intune will notify you if there are devices that could 't be expedited, together with reasons and mitigations. Note: We're exploring a future capability to test the expedite capability without needing to create an expedite policy for a quality update."

Microsoft says this program happens to be focused specifically on security updates, but at the same time, the organization reveals that it's also working on an identical approach specifically aimed at non-security patches. This expansion will make it possible for organizations to urgently deploy certain bug fixes and enhancements on their Windows 10 and Windows 11 devices, whilst enforcing a time to reboot for every machine.

Microsoft appears to be focusing on a new system optimization solution that will more or less look like CCleaner, the famous app that's already on Windows.

Called PC Manager, Microsoft's new tool is expected to come with features that clearly remind of CCleaner, including handling the storage, checking out the running processes, and managing the applications designed to run at boot.

As noted by The Verge, a few of these features already are part of the default Windows experience, but Microsoft has become creating a dedicated app which brings everything under one roof.

At this time, the app is available using a Chinese Microsoft site, so it's not entirely clear exactly what the company's plans for PC Manager currently are so when we can expect the app to visit live for Windows 10 and Windows 11 users.

Here is the feature lineup of CCleaner to fully understand what a system optimization solution is designed to do:

Standard privacy protection
Standard cleaning
Performance Optimizer
Driver Updater
Complete PC Health Check
Updates apps to reduce security risks
Complete cleaning
Keeps your browsing history private
Detects and removes internet trackers
Keeps you against running out of space
Priority customer support

"Inject instant speed into your machine by freezing resource-hogging apps and programs by removing the unnecessary files taking on room in your hard drive. Clear out errors, broken settings, increase drivers to improve stability. Protect your privacy by securely erasing tracking cookies and history," parents company says.

Of course, it'll be interesting to see if Microsoft is indeed trying to build a fully featured alternative to CCleaner or the company just really wants to move some system features out of the Settings app, but for now, it's remained completely tightlipped on this mysterious bit of software.

Microsoft's Moment 1 update for Windows 11 2022 Update comes with one little surprise (though we knew it had been coming anyway): support for Android apps.

That's right, users are now able to run Android apps on their Windows 11 devices, once they are based in one of the 31 support regions, including the Usa, the uk, France, Germany, yet others.

The Android app support on Windows 11 is run by the Amazon Appstore app, which is now rolling out on devices running the 2022 update as well.

Needless to say, users should also run the Windows Subsystem for Android, and Microsoft says it's been spending so much time with developers to make sure enough apps are for sale to users.

The amount of Android apps on Windows 11 keeps growing

So right now, the feature comes with approximately 50,000 titles, including apps and games.

"Through our partnership with Amazon, you can now access Android apps and games from the Amazon Appstore, generally available in 31 countries, including Australia, Canada, France, Germany, Italy, Japan, Spain, United Kingdom, United States and much more," Microsoft explains.

"With 50 plus,000 titles to select from, it's simple to discover and download your favorite apps and games on your Windows device, such as Project Makeover, Evony: The King's Return, Coin Master, Kindle, Audible, FlipaClip, Lutron and so many more. Enabled by Windows Subsystem for Android?, developers are in possession of even more methods to bring their apps and games to Windows."

The Moment 1 update is currently available as a preview update, so users need to manually check out Windows Update and appearance for updates. Microsoft, however, will start the automated update the following month as part of the Patch Tuesday cycle once the update will show up on Windows Update for those devices alongside other security improvements.
