How to Fix: Windows Update failed, system now failing to boot

Windows Update failure and blue screen with CRITICAL_SERVICE_FAILED error.

Quick Answer: Run a clean boot to isolate the issue, then check for corrupted system files using SFC /SCANNOW and DISM /Online /CleanupImage /RestoreHealth.

Windows Update failure can be caused by a variety of factors, including corrupted system files, outdated drivers, or conflicts with other software. In your case, the blue screen error and failed DISM and sfc scans suggest that there may be issues with the Windows installation itself.

  1. Step 1: Open Command Prompt as Administrator and type the command `sfc /scannow` to scan for corrupted system files.

Method 2: System Restore

  1. Step 1: Open Control Panel and select System and Security, then click on System Protection. Select the system drive and click on System Restore.

💡 Conclusion

After resolving the issue using one of the methods above, restart your computer and check if Windows Update is working correctly. If you are still experiencing issues, consider performing a clean installation of Windows.
