New updates have been released to the Windows 11 Beta channel with KB5016700. You can now upgrade your operating system’s build to either 22522.450 or 22621.450, depending upon which group your device is a part of.

The users on the Beta channel were earlier divided into 2 groups where one group received updates with the new features enabled (Build 22622) and the other with the features disabled by default (Build 22621).

This flight does not include any new features but makes several fixes and improvements. Let us now discuss the new improvements in this flight and how you can install them.

Reminder: The users who landed in the group with new features disabled by default (Build 22621) can check for updates manually and choose to install the update that will have the features enabled (Build 22622).
