To fix it: run the Windows Update Troubleshooter (Settings → Update & Security → Troubleshoot → Windows Update); open Command Prompt as administrator and execute
DISM /Online /Cleanup-Image /RestoreHealth
followed by sfc /scannow
to repair system file integrity; then reset the update cache by stopping the Windows Update services (net stop wuauserv
and net stop bits
), renaming the SoftwareDistribution
and catroot2
folders, restarting the services, rebooting, and retrying Windows Update. If issues persist, create a clean local administrator account and attempt the update from that profile.For complete step‑by‑step guidance and advanced troubleshooting strategies, check this Windows Update error 0x8007370B fix guide.
