How to fix error error-registry-corrupt in Windows 11

Solution Steps

1. 1 First, try to boot into Safe Mode. Restart your PC and press F8 (or Shift + F8) repeatedly before the Windows logo appears. If that doesn't work, use the Recovery Environment: restart, and when the login screen appears, hold Shift and click the Power icon, then select 'Restart'. Navigate to Troubleshoot → Advanced Options → Startup Settings → Restart, then press 4 for Safe Mode. Safe Mode loads only essential drivers, which can help you access the system if the corruption is severe.
2. 2 Once in Safe Mode, press Windows key + R, type 'regedit', and press Enter. This opens the Registry Editor. Go to File → Export to back up the entire Registry. Save it to a safe location. This is your safety net — if something goes wrong, you can restore this backup.
3. 3 Run the System File Checker. Press Windows key + X and select 'Terminal (Admin)'. Type 'sfc /scannow' and press Enter. This will scan and repair corrupted system files, which might also fix Registry issues.
4. 4 If SFC doesn't help, use DISM. Type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. This repairs the Windows system image, which can indirectly fix Registry corruption.
5. 5 If the Registry is still corrupted, you may need to perform a System Restore. Press Windows key + R, type 'rstrui', and press Enter. Follow the wizard to restore your PC to a point before the corruption occurred. This will revert Registry changes to a previous state.
