How to Fix
Step-by-Step Solutions
- Open Settings → Update & Security → Troubleshoot → Additional troubleshooters → Windows Update
Launch the built‑in troubleshooter to automatically detect and fix common update problems.
- Run DISM to repair the component store
DISM scans the Windows image for corruption and replaces damaged files.
DISM /Online /Cleanup-Image /RestoreHealth - Run SFC to verify and repair system files
SFC checks all protected system files and restores them if needed.
sfc /scannow - Reset Windows Update components
Stop services, rename SoftwareDistribution and Catroot2 folders, then restart services to clear stale data.
net stop wuauserv && net stop bits && net stop cryptsvc && net stop msiserver && ren C:\\Windows\\SoftwareDistribution SoftwareDistribution.old && ren C:\\Windows\\System32\\catroot2 Catroot2.old && net start wuauserv && net start bits && net start cryptsvc && net start msiserver - Delete the SoftwareDistribution folder
Removing the folder forces Windows to rebuild the update cache, eliminating corrupted downloads.
rd /s /q C:\\Windows\\SoftwareDistribution - Check date and time settings
