Microsoft releases KB5022836 update to fix Windows 11 21H2 security issues

It is the time of the month when Microsoft releases updates for Windows, and as such the company has released a pair of patches for Windows 11. Specifically, we have two cumulative updates in the form of KB5022845 for Windows 11 22H2 and KB5022836 for Windows 11 21H2.

The KB5022836 update takes Windows 11 up to build 22000.1574, and it also includes the changes and improvements that were part of the KB5019274 update preview released last month.

As is usually the case with security-focused cumulative updates, Microsoft does not provide specific details about everything that is addressed by KB5022836. The company says only that it "addresses security issues for your Windows operating system", and that it "makes miscellaneous security improvements to internal OS functionality".
