Optional Updates Are Out for All Windows 10 Supported Versions with New Features and Bugfixes!

Microsoft has released the March 2022 non-security preview “C” release updates for all supported versions of Windows 10. As tagged by the company itself, these updates are in “preview,” which means you can avoid installing them on your devices.

All the fixes and improvements that are released through these preview releases are packaged with next month’s mandatory Patch Tuesday updates for Windows. Today’s optional updates are available for Windows 10 21H2, 21H2, and 20H2. KB5011543 (Builds 19042.1620 for v20H2, Build 19043.1620 for v21H1, and Build 19044.1620 for v21H2) introduces Search highlights (something from Windows 11. released earlier for Insiders), along with several other improvements.
