DISM /Online /Cleanup-Image /StartComponentCleanup

Uninstalling the Cumulative Update

If you face issues after upgrading to KB5034765, it is possible to uninstall the cumulative update package with a few steps. However, this reverts your Windows version to the previous unpatched state.

To remove KB5034765:

dism /online /remove-package /packagename:Package_for_KB5034765~31bf3856ad364e35~amd64~~22631.3155.1.5

Replace Package_for_KB503476531bf3856ad364e35amd64~~22631.3155.1.5 with your actual cumulative update package name discovered from the first command.

This will uninstall KB5034765 from your system fully. Follow it up with mandatory restarts.
