Windows 10 update KB5005611 out for versions 21H1, 20H2, 2004 (preview)

Microsoft releases previews of the next fixes for Windows 10 versions 21H1, 20H2, 2004, and older releases like 1909 and 1809.

As part of the release “C,” Microsoft is making available the update KB5005611 for Windows 10 21H1, 20H2, and 2004 as an optional install in the stable channel. This is a non-security update meant to address a slew of problems with the last three most recent releases of the OS. 

The update bumps the version number to builds 19041.1266, 19042.1266, and 19043.1266, depending on the version, and it introduces fixes for “news and interests,” Cortana, restart, apps, and more.

Previously, this update was only available in the Release Preview Channel for version 21H1.
