Server 2012 Windows Update Not Working – CBS called Error with 0x800f0922

Today I came across a Windows 2012 Server where Windows Update was not working. The server would go to install the updates get about 90% through and then error. On inspection of the WindowsUpdate.log file located in C:\windows. There was the error below :-

Handler FATAL: CBS called Error with 0x800f0922
CBS Error

In order to resolve the problem I ran the following lines from an elevated command prompt :

fsutil resource setautoreset true C:\

Followed by

DISM /online /Cleanup-Image /restorehealth

This command will sit at 20% for ages. Do not stop this process and let it complete. It can take a while to complete.

Once complete you should be good to go 🙂
