Fixing Windows Update Error Code 8007370A
Error 8007370A typically appears when the Windows Update client detects corrupted component store files or missing system files required for update installation—often caused by interrupted updates, file corruption, or component store failures. This issue prevents crucial updates from being installed, leaving your system exposed. To resolve it, begin by running the Windows Update Troubleshooter (Settings → Update & Security → Troubleshoot → Additional troubleshooters) to let Windows automatically diagnose and fix common issues. Next, clear the update cache: stop the Windows Update, Background Intelligent Transfer Service (BITS), and Cryptographic Services, then delete all files inside C:WindowsSoftwareDistribution and C:WindowsSystem32catroot2. After clearing, restart the services and your computer. Then open an elevated Command Prompt and run sfc /scannow to repair corrupted system files, followed by DISM /Online /Cleanup-Image /RestoreHealth to repair deeper component store issues. If issues persist, run DISM /Online /Cleanup-Image /ScanHealth and DISM /Online /Cleanup-Image /CheckHealth to verify component store integrity and repeat the RestoreHealth process if needed. Finally, reboot your system and rerun Windows Update. For a complete, step‑by‑step troubleshooting walkthrough, see this detailed guide.
