Windows Update shows an error and won't install
Windows Update errors are caused by corrupted update files, not enough disk space, or a service that got stuck. Restarting the Update service and clearing the cache fixes most errors.
Windows Updates fail when the Update service finds corrupted files, runs out of disk space, or gets stuck. Most errors go away by restarting the Update service, clearing out old update files, and trying again. If you keep getting the same error, the error code itself tells you what is wrong.

Skip — I just want a technicianCommon mistakes to avoid
- Shutting down your computer during an update installation (when it shows a blue Installing screen) — this breaks the update and causes bigger problems on the next restart
- Retrying the update immediately without clearing the cache — you are just trying the same broken files again
- Ignoring the error code and just trying again — the code tells you exactly what is wrong
Signs you need professional help
- If the error persists after clearing the cache, restarting the service, and freeing disk space
- If you see a blue Automatic Repair screen after restart — the update installation was interrupted
- If System File Checker finds and repairs files but the error keeps happening
