Fix Windows Update Error 0x800f0922 on Windows 11 24H2
Windows 11 24H2 failing with 0x800f0922? It's usually a full EFI system partition or corrupt files. Repair the component store or free space — steps here.
Windows Update error 0x800f0922 on 24H2 usually means one of two things: the small EFI system partition is too full for the update to stage, or the component store is corrupt. Repairing the system files fixes most cases; a full EFI partition needs a little space freed.
Try the repair commands first
Most 0x800f0922 failures clear with a component-store repair. Open Terminal as administrator and run DISM /Online /Cleanup-Image /RestoreHealth, let it finish, then sfc /scannow. Reboot and retry the update. Also run the Windows Update troubleshooter under Settings, System, Troubleshoot, Other troubleshooters, which resets the update services.
| Cause | Sign | Fix |
|---|---|---|
| Corrupt component store | Fails after download | DISM + SFC |
| Full EFI system partition | Fails staging the update | Free/resize the EFI partition |
| Broken update services | Repeated failures | Run the update troubleshooter |
When the EFI partition is full
24H2 needs room in the roughly 100 MB EFI system partition to stage boot files, and a partition left near-full by earlier updates throws 0x800f0922. This one is fiddly because the EFI partition has no drive letter; a partition tool (a free one such as MiniTool or EaseUS) can show its free space and expand it. If you would rather not touch partitions, an in-place repair upgrade from a Windows 11 ISO installs the update while keeping your files and apps.
If it still fails
Clear the update cache: stop the Windows Update and BITS services, rename the SoftwareDistribution folder, start them again, then retry. If a single update keeps failing, you can pause updates while you sort it out, or remove a half-installed one — see a stuck Windows Update and uninstalling a Windows update. Freeing general disk space helps too; how to free up space on Windows 11 covers the safe ways.
Common questions
What does error 0x800f0922 actually mean?
It is a servicing failure: Windows could not apply the update, usually because the component store is corrupt or the EFI system partition has too little free space to stage the update.
How do I free space on the EFI system partition?
The EFI partition has no drive letter, so use a partition tool to see and expand it, or run an in-place repair upgrade from a Windows 11 ISO, which sidesteps the space limit while keeping your files.
Do DISM and SFC fix 0x800f0922?
Often, yes — DISM /Online /Cleanup-Image /RestoreHealth then sfc /scannow repairs the corrupt component store behind most cases. Reboot and retry the update afterward.
The update keeps failing at the same point — what next?
Clear the SoftwareDistribution cache, run the update troubleshooter, and if it still fails, do an in-place repair upgrade from an ISO, which reinstalls Windows over itself and applies the update.
