Cindy, I have tried the troubleshooting steps listed by David M. here as this person had a similar issue to me. Windows 11 Update (KB5012592) fails With Error Code 0x800f0900 - Microsoft Community I have tried all of them, I did find corrupted files and I ran windows update troubleshooter. All with no luck.

 

Can't install KB5016616. Error 0x800f0900

When I tried to install KB5016688 I got the following failure messages in the CBS.log :

I think that I can thus limit the problem to a conflict with KB5012170.

Windows Update says in the system settings that this Update (KB5012170) has been successfully installed.

I tried uninstalling KB5012170 in Windows, in Win RE with wusa and with dism, but by none of this ways I could deinstall it. I planned to reinstall it after the deinstallation, because perhaps this would have fixed the corruption.

Furthermore, running dism in WinRE with /Cleanup-image /Restorehealth also produced the error code 0x800f081f.
