Hi there,
I have a Windows Server 2012 R2 keep failing on Windows Updates for 3 patches (KB5012639, KB5014001 & KB5016681) with the error code 800F0831.
I tried to remove cache, manually downloading the patches to install but still no luck. Do you have any idea for this error?
I did "sfc/ scannow" and confirmed there's no invalid system file.
FYR.
Thank you
Johnny

Some things to try
https://learn.microsoft.com/en-us/windows/deployment/update/windows-update-resources#reset-windows-update-components-manually
sfc /scannow
dism /online /cleanup-image /restorehealth
a repair install by running setup.exe from the root of install media

Just checking if there's any progress or updates?

Thank you for your reply! I have tried both, restarted the server and ran the Windows update again but still got the same error code.
If the repair install also fails then time may be better spent standing up a new one for replacement, patch fully, migrate roles over, and move on.
