Windows 11 may be making headlines lately, but it's important to remember that Windows 10 21H2 is geared toward the public. Microsoft has not yet given an official release date, but the final version has reached the channel Preview release recently.
The Windows 10 of version 20H2 were released on October 20, 2020, which means we can expect the 21H2 version sometime in October.
Version 21H2 is supposed to be a relatively minor upgrade, but it is important for computers that do not meet Microsoft requirements for Windows 11. Some have been forced to install Windows 11 and may not be able to receive security updates. So the Windows 10 21H2 update is a good choice if something goes wrong with Windows 11.
The upcoming Windows 10 operating system of version 21H2 is an activation package, just as version 21H1 was for version 20H2. This basically means that the "new" features available with this update already exist in version 21H1, but in idle mode. Your computer is not going to get any new features, but this update will just show some features that already exist.
In terms of features that will appear will not be many. When Microsoft announced some details about the update in July, it mentioned a total of three features that will be enabled in Windows 10 of version 21H2.
1. The operating system will support WPA3 H2E standards for increased Wi-Fi security. H2E stands for "Hash-to-Element" and is an improvement over the Wi-Fi Protected Access III (WPA3) standard. According to Cisco, the WPA3 H2E is computationally much more efficient than its predecessor and is also resistant to side channel attacks used by malicious users to steal credentials.
2. Microsoft has added a new method of using Windows Hello for Business called cloud trust. If you are wondering what is the difference between normal Windows Hello that you can use on your personal computer and Windows Hello for Business: The former is used by consumers to create a PIN or biometric gesture as an alternative connection method. Windows Hello for Business, on the other hand, is used by businesses and configured using group policies or portable management (MDM) policies. It always uses asymmetric certification, which makes it much more powerful in terms of security.
Finally, the third feature that Microsoft will feature in Windows 3 version 10H21 is GPU compute support in Windows Subsystem for Linux (WSL) and Azure IoT Edge for Linux on Windows (EFLOW).
This is done to facilitate the machine learning that requires resources.
