Microsoft releases an optional update for Windows 11 with a number of fixes

The April 2022 Non-Security Preview Update marked as a “C” version is now available for Windows 11. This is an optional update in preview, which means you’ll have to wait until next month’s patch Tuesday updates to get the fixes delivered today to avoid No surprises. However, if there is a specific issue that bothers you and it is addressed in this release, you can get the update via Windows Update or manually through the update catalog.

Preview updates are also available for supported versions of Windows 10, including KB5011831 released for builds 20H2, 21H1, and 21H2 (versions 19042.1682, 19043.1682, and 19044.1682, respectively).
