Situatie

The error 0x000000EF in Windows 11 is the CRITICAL_PROCESS_DIED blue screen. It means an essential system process crashed—usually due to corrupted files, bad drivers, or disk issues.

Solutie

If you’re stuck in a restart loop:

  1. Force shutdown your PC 3 times
  2. On the 4th boot → Windows Recovery appears
  3. Go to:
    • Troubleshoot → Advanced options → Startup Settings → Restart
    • Press 4 for Safe Mode

2. Repair system files

Open Command Prompt (Admin) and run:

sfc /scannow

Then run:

DISM /Online /Cleanup-Image /RestoreHealth

This fixes corrupted Windows components (a very common cause of this error).

3. Check your disk for errors

Still in Command Prompt:

chkdsk C: /f /r
  • Press Y and restart
  • This scans for bad sectors or disk corruption

4. Update or reinstall drivers

Faulty drivers (especially GPU/storage) often trigger this.

Update drivers from:

  • NVIDIA
  • AMD
  • Intel

Best practice: uninstall the driver first, then install the latest version.

5. Uninstall recent updates or apps

If the error started recently:

  • Go to:
    • Settings → Windows Update → Update history → Uninstall updates
  • Or remove recently installed software (especially antivirus tools)

6. Check RAM

Bad memory can cause this crash.

  • Press Win + R → type:
mdsched.exe
  • Restart and scan

7. Disable Fast Startup

  • Control Panel → Power Options → Choose what power buttons do
  • Turn OFF Fast Startup

8. System Restore

  • Go to Recovery → Open System Restore
  • Pick a restore point before the issue started

 9. Last resort: Reset Windows

  • Settings → System → Recovery → Reset this PC
  • Choose Keep my files.
