How to Fix Critical Process Died on Windows

What Causes This?

The Critical Process Died blue screen usually means an essential Windows system process stopped unexpectedly. This can happen because of corrupted system files, faulty drivers, bad updates, disk errors, or failing hardware such as an SSD or RAM. In some cases, aggressive cleanup tools, antivirus conflicts, or damaged temporary files can also trigger system instability after startup or during shutdown.

Common Symptoms

• A blue screen appears with the message Critical Process Died
• Windows restarts automatically and may get stuck in a boot loop
• The PC crashes shortly after signing in
• Apps freeze or stop responding before the crash
• Windows Recovery or Automatic Repair opens instead of normal startup

How to Fix It Manually

1. Boot into Safe Mode

   • If Windows still starts, press Windows + I > System > Recovery > Advanced startup > Restart now.
   • If Windows will not start, interrupt boot 3 times in a row to open Windows Recovery Environment.
   • Go to Troubleshoot > Advanced options > Startup Settings > Restart.
   • Press 4 for Safe Mode or 5 for Safe Mode with Networking.

2. Run System File Checker and DISM

   • In Safe Mode, right-click Start and choose Terminal (Admin) or Command Prompt (Admin).
   • Run this command:

     sfc /scannow

   • Wait for it to finish, then run:

     DISM /Online /Cleanup-Image /RestoreHealth

   • Restart your PC normally after both scans complete.

3. Check your disk for errors

   • Open Terminal (Admin) again.
   • Run:

     chkdsk C: /f /r

   • If asked to schedule the scan on restart, type Y and press Enter.
   • Restart the PC and let the scan finish. This can take a while.

4. Remove recent drivers, updates, or software

   • Press Windows + X > Device Manager.
   • Look for devices with a warning icon, or recently updated drivers.
   • Right-click the device > Properties > Driver > Roll Back Driver if available.
   • To remove a recent Windows update, go to Settings > Windows Update > Update history > Uninstall updates.
   • Also uninstall any recently added antivirus, tuning tools, or system cleaners from Settings > Apps > Installed apps.

5. Use System Restore if the crashes started recently

   • Open Windows Recovery Environment again.
   • Select Troubleshoot > Advanced options > System Restore.
   • Choose a restore point from before the blue screen started happening.
   • Follow the prompts and let Windows restore system settings and drivers.

6. Clean up temporary files after recovery

   • Once Windows is stable again, open Settings > System > Storage > Temporary files.
   • Review the list and remove unnecessary temporary files, update leftovers, and cache files.
   • This helps clear damaged junk files that may contribute to instability and frees up space for updates and repairs.
