Solution Steps
- 1 Boot into Safe Mode: Restart your PC and press F8 (or Shift + Restart) to access Advanced Startup Options. Choose Safe Mode with Networking. This loads minimal drivers and services, allowing you to access the system to perform repairs.
- 2 Run System File Checker: Open Command Prompt as administrator (right-click Start → 'Terminal (Admin)'). Run 'sfc /scannow' to repair corrupted system files, including registry-related files.
- 3 Run DISM: In the same Command Prompt, run 'DISM /Online /Cleanup-Image /RestoreHealth'. This repairs the Windows system image, which can fix registry corruption.
- 4 Check disk for errors: Run 'chkdsk /f /r' on your system drive. This scans for and repairs disk errors that could be causing registry corruption. You'll need to restart to let the scan run.
- 5 Restore the registry from backup: If you have a system restore point, use System Restore to revert to a previous state. Press Windows key + R, type 'rstrui.exe', and press Enter. Follow the wizard to choose a restore point.
