Laptop running Windows 11

With Patch Tuesday having rolled around once again, Microsoft has issued its regular batch of releases. We've already talked about the KB5022836 update for Windows 11 21H2, but if you're running Windows 11 22H2, you will need the KB5022845 update instead.

The KB5022845 update takes Windows 11 up to build 22621.1265, and it also includes the changes and improvements that were part of the KB5022360 update preview released last month.
