Windows Update error 0x8007371B typically occurs when the update process can’t access or install necessary system files—often due to corruption or missing components. To resolve it:
1. Reset Windows Update components: Run an elevated Command Prompt and stop services (
wuauserv, bits, cryptsvc), rename the SoftwareDistribution and Catroot2 folders, then restart the services.2. Run the Windows Update Troubleshooter: Navigate to Settings → Update & Security → Troubleshoot → Windows Update to let Windows automatically detect and fix issues.
3. Repair system files: In the same Command Prompt window, run
sfc /scannow to scan for and fix corrupted files.4. Temporarily disable antivirus/firewall software: Security programs can block update files—turn them off during the update process, then re-enable once updates complete.
After completing these steps, restart your PC and attempt the update again. For a full, detailed troubleshooting walkthrough, visit this guide.
