However, most corporate users may stick to Windows 10 until the new operating system bug is fixed. Microsoft will continue to release feature updates such as Windows 10 21H2 until October 2025. Therefore, businesses and consumers can upgrade to Windows 11. 

“Windows 10 version 21H2 will have a set of special features focused on performance and security. Since most of the new features will be in Windows 11, Microsoft will release limited Windows 10 in the future. We prioritize customer satisfaction based on feedback,” said John Cable, Microsoft’s vice president of project management.

However, Windows 10 version 21H2 is providing new feature updates for Windows Insiders who move from beta to launch because their PCs do not meet the system requirements of Windows 11. 

Microsoft will only provide to “search engines” or users who are looking for manual updates through Windows Update for these users. After the update is installed, Windows 10 will be updated to build 19044.1147. 

Windows 10 21H2 is the long-term service channel (LTSC) version, which means it will provide support within 30 months after its release. 

What’s New in Windows 10 21H2? 

Compared to Windows11, Windows 10 21H2 is not the best version, but it will include some new productivity and business features. In this version, Microsoft added support for WPA3 H2E (HashtoElement), which provides enhanced protection against side-channel attacks and reduces the risk of side-channel attacks in the future. 

Also, Windows 10 21H2 includes GPU computing, which is the most needed feature for Windows Subsystem for Linux and Azure IoT Edge for Linux for Windows. This feature allows you to use the installed graphics card to “accelerate mathematical workloads and use its parallel processing to perform the required calculations. 

In many cases, it runs faster than using a single processor. To use this feature, you must install HyperV and WSL2. Finally, this feature update simplifies the deployment of new computers with predefined security policies by supporting a passwordless deployment model. 

Additionally, they are improving Windows Hello for Business. According to Microsoft, they have not included some of these features in Windows 10 21H2. Perhaps, it will be available in a future version.
