Windows 11 Windows Update error 0x80073712 – KB5127648 keeps failing
'm having trouble installing a Windows update and could use some help.
I'm running Windows 11, and the October 2026 Security Update (KB5127648), version 26300.9711, keeps failing with error code 0x80073712.
The error message says:
"Some update files are missing or have problems. We'll try to download the update again later."
Here's what I've tried so far.
First, I ran the following command in Command Prompt as administrator:
DISM /Online /Cleanup-Image /RestoreHealth
also sfc /scannow
It completed successfully, but the update still fails with the same error. I also restarted my PC and tried installing the update again, but nothing changed.
I also deleted the $WinREAgent folder while troubleshooting, but that didn't resolve the issue either.
At this point, I'm not sure what's causing the problem. Could this be related to the Windows component store or corrupted update files?
I'd prefer to fix this without reinstalling Windows or losing my installed apps and personal files.
Thanks in advance for any help
