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 release preview 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's important for PCs that don't meet Microsoft's requirements for Windows 11. Some have force-installed Windows 11, and it's quite possible that they won't be able to get security updates. So Windows 10 21H2 update is a good option if something goes wrong with Windows 11.
The upcoming Windows 10 version 21H2 OS is an activation pack, just like version 21H1 was for version 20H2. This essentially means that the “new” features available with this information they already exist in version 21H1, but in an inactive state. Your PC isn't going to get any new features, but this update will just add some features that are already there.
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 enhancement of the Wi-Fi Protected Access III (WPA3) standard. According to Cisco, 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 added a new method of using Windows Hello for Business called cloud trust. If you're wondering what the difference is between regular Windows Hello that you can use on your PC versus Windows Hello for Business: The former is used by consumers to create a PIN or biometric gesture as an alternative sign-in method. On the other hand, Windows Hello for Business is used by businesses and configured using policies teams or mobile device management (MDM) policies. It always uses asymmetric authentication, which makes it much stronger 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 which requires resources.
