The Windows 10 21H2 feature update is a limited release with only a few new features, aimed primarily at business users.

What’s new in the Windows 10 21H2 feature update?
As we said above, it is one of the smaller feature updates and brings only a few new features.
First, Microsoft is now adding support for the WPA3 H2E (Hash-to-Element) protocol, which provides increased protection against side-channel attacks.
In 2019, security researchers disclosed a new side-channel attack called “DragonBlood” that could be used to steal a WPA3 password.
After the disclosure of the vulnerability, the Hash-to-Element protocol was added to WPA3’s Simultaneous Authentication of Equals (SAE) authentication protocol to prevent these types of attacks.
Windows 10 21H2 also includes the long-awaited GPU compute feature in the Windows Subsystem for Linux and Azure IoT Edge for Linux and Windows.
GPU compute was the feature that users wanted most for WSL and allows Windows users to use their graphics card to “accelerate math-heavy workloads”.
