The March 2022 non-security preview release, referred to as our “C” release, is now available for Windows 11 and other supported versions of Windows. Information about the contents of this update is available from the release notes, which are accessible from the Windows 11 and Windows 10 update history pages. To learn more about the different types of monthly quality updates, see our Windows 10 quality updates primer.
Improvements and Fixes for Windows 11:
- Displays up to three high priority toast notifications simultaneously. This feature is for apps that send notifications for calls, reminders, or alarms using Windows notifications in the OS.
- Addresses an issue that turns off auto-startup for Universal Windows Platform (UWP) apps after you upgrade the OS.
- Addresses an issue that causes SystemSettings.exe to stop working.
- Addresses an issue that affects searchindexer.exe and prevents Microsoft Outlook’s offline search from returning recent emails.
- Addresses an issue that increases the startup time for Windows. This issue occurs because a UI thread in a networking API stops responding when a 5G wireless wide area network (WWAN) device is slow to wake up.
- Addresses a memory leak in the wmipicmp.dll module that causes a lot of false alarms in the System Center Operations Manager (SCOM) datacenter monitoring system.
