Windows 10: I get error 0x800700a1 when I try to use Windows Update. I've done the DISM commands as...

I've used the Windows Creation Tool to create an installation USB drive N, and I ran the following commandISM.exe /Online /Cleanup-Image /RestoreHealth /Source:N:\It did its thing, then I did:sfc -scannowAnd it found some problems, it said it fixed them, but when I tried doing a Windows Update again, it gave the same error.I'm just at a loss of what to do. I've considered trying to upgrade to Windows 11, and hope that would take care of the issue during the upgrade, but I'm pretty hesitant in losing both functionality and efficiency.Perhaps I should be happy that I can't get Windows Updat

Windows 10 fails to update


Thanks,

The Users list compared to the Profile list you posted earlier tell me there is not an issue with Users (a known issue where there is a profile in the list, but not actual User folder).

The error code suggests corruption in the CBS manifest:
