What to do? For the second time Windows Update that failed?
This error code, 0x800f0922, can be quite frustrating since there could be several possible causes for this error code. After having already used the Windows Update Troubleshooter and deleted content from the SoftwareDistribution folder, here are some more things that can be done to solve this error without a complete reset or in place upgrade. Run DISM and SFC scans; Right click on Command Prompt and execute the following: ``` DISM /Online /Cleanup-Image /RestoreHealth sfc /scannow ``` Wait for both scans to be done and then restart the PC and repeat the update process. Here are the steps to verify the System Reserved / EFI partition: A frequent cause of error code 0x800f0922 is that there is not enough free space in either the System Reserved partition or the EFI partition. Windows may not install if your system partition gets full while the installation is in progress. Disk Management can be used to view partition sizes. 3. Turn off the third party security software for a while Cumulative updates may be interfered with by avalanche protection software or endpoint protection software. Switch it off for a while and try to install again. 4. Disconnect VPNs, and verify network connectivity. Unplug your VPN, proxy or restrictive firewall if you use it before you run Windows Update. This error sometimes happens during installation because Windows can't access the Microsoft Update services. 5. Manually install the update: Check Windows Update History for the KB number of the failed update to download directly from Microsoft Update Catalog. Sometimes manual installation will work where Windows Update will not. To check the CBS and Windows Update logs: Looking at the logs, if it still doesn't work, it will be possible to determine which component is failing. The general error code may not be as specific as the information in the Event Viewer and the CBS.log file. I would suggest to try the DISM/SFC and see if the EFI/System Reserved partition size is okay before resetting the PC or considering a repair install. The two regions are among the most frequent places where the failures 0x800f0922 can reoccur. Have you got the exact KB number of the update that is failing and is your system UEFI/GPT or Legacy BIOS? The information can be used to help focus on the underlying cause.
