Windows 11 KB5023778 adds improved taskbar search bar, Microsoft Account notifications, more

If you use a stable Windows 11 release and do not mind installing a cumulative update a little earlier than others, here is a new release from Microsoft for you. KB5023778 (build 22621.1485) is now available with several notable changes and non-security fixes.

As a reminder, Microsoft is changing how it delivers preview versions of its cumulative updates. Beginning April 2023, the company will ship optional non-security updates every fourth Tuesday of the month. In other words, users now have two Patch Tuesdays—one mandatory and one optional.
