 Error Code 0x8000ffff.webp)
Windows Update Error Code 0x8000FFFF can appear when Windows fails to download, install, or complete an update, or when Windows components can’t be updated correctly. It can affect both Windows 10 and 11.
Common causes include corrupted system files, damaged Windows Update components, incomplete downloads, third-party software interference, network problems, or insufficient disk space. You don’t usually need to reset Windows to fix this — this guide covers the solutions in order.
What Causes Windows Update Error Code 0x8000FFFF?
Common causes include corrupted or missing system files, damaged Windows Update components, incomplete or corrupted downloads, problems with update services, third-party antivirus interference, network or proxy configuration problems, insufficient free storage, or temporary update cache issues. Start with the Windows Update troubleshooter, then repair the installation and reset the update components if needed.
Here’s how to fix Error Code 0x8000FFFF:
Run the Windows Update Troubleshooter
Windows 11: Settings → System → Troubleshoot → Other troubleshooters → Windows Update → Run.
Windows 10: Settings → Update & Security → Troubleshoot → Additional troubleshooters → Windows Update → Run the troubleshooter.
Restart your computer once it finishes, then check for updates again.
Run DISM and SFC
Open Command Prompt as administrator and run DISM.exe /Online /Cleanup-Image /RestoreHealth. Wait for it to complete, then restart your computer. If update files are also reported as missing or corrupted, see our guide to Windows Update Error Code 80073712. Then open Command Prompt as administrator again and run sfc /scannow, letting it reach 100%. If corrupted files were repaired, restart and try the update again.
Restart Windows Update services
Open Command Prompt as administrator and run:
net stop wuauserv
net stop bits
net stop cryptSvc
net stop msiserver
Then start them again:
net start msiserver
net start cryptSvc
net start bits
net start wuauserv
Restart your computer and check for updates.
Reset the Windows Update cache
Stop the services listed above, then rename the cache folders:
ren %windir%\SoftwareDistribution SoftwareDistribution.old
ren %windir%\System32\catroot2 catroot2.old
Restart the services, then restart your PC and check for updates — Windows will create fresh folders as needed.
Check your internet connection
Restart your router, temporarily disconnect from any VPN, check whether other websites load normally, try another network if available, and temporarily check whether security software is interfering. Don’t permanently disable your antivirus or firewall — restore any temporary changes afterward. For connection-related problems specifically, see our guide to Windows Update Error Code 0x8024402C.
Check available storage
Go to Settings → System → Storage and remove unnecessary temporary files or applications if your drive is running low. For storage-related failures specifically, see our guide to Windows Update Error Code 0x80070070.
Temporarily perform a clean boot
Press Win + R, type msconfig, press Enter. Go to the Services tab, check “Hide all Microsoft services,” click “Disable all.” Go to Startup, open Task Manager, disable unnecessary items, restart, and try the update. Return to your normal startup configuration afterward.
Install the update again
Go to Settings → Windows Update → Check for updates, restart, and check once more to confirm no errors remain. If one specific update keeps failing, note its KB number and search for it in the Microsoft Update Catalog for a standalone package.
Use Windows Recovery or a repair installation
If the error continues, check Settings → System → Recovery for “Fix problems using Windows Update” on Windows 11. For persistent corruption, an in-place repair using official installation media may help — back up important files first. A full “Reset this PC” should be a last resort, not the first solution.
Still Not Resolved?
Start with the troubleshooter, then run DISM and SFC, restart the update services, and reset the cache. Check your connection and storage next, and use Windows recovery or a repair installation before considering a full reset.
