    Hi,

    I had the same problem. I first deactivated Malwarebytes but this did not resolve the problem. I then turned off .Net 3.5 and restarted my device. Then installed the 2002-07 Cumulative update KB 5015814 for Windows 11 via Check for updates and IT WORKED !! It took longer to download and install than usual but IT WORKED. I then reactivated .NET 3.5 and Malwarebytes.

    For me it sounds it was a problem with .Net 3.5 since deactivating Malwarebytes only did not do the job.

    I hope it helps others.

    I had the same problem, and none of the tips found on the internet helped. Sfc, dism, manual install from the catalog, etc... No success. Even an in-place upgrade with the win11 ISO did not work.

    What finally worked for me, is to do this in-place upgrade, after disabling all non-microsoft services.

    • download win11 ISO
    • run msconfig: > on the tab General, chose Selective Startup, with only Load System Services checked, > on the tab Services, check Hide Microsoft Services, and then Disable All.
    • mount the ISO, run setup.exe
    • let the installer do its job, keep apps & files. takes some time ...
    • when done, run msconfig again and re-enable all non-microsoft services

    After all this, win update shows that KB5015814 is successfully installed.

    Hope this helps others!
