What You’ll Need

Step-by-Step

1. Identify the Cause of the Error
   Open Task Manager (Ctrl + Shift + Esc) and look for werfault.exe. Check if it’s consuming high CPU or memory, which indicates a problematic process or service.

   In the same Command Prompt window, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This repairs Windows system images that SFC might not fix.

7. Perform a Clean Boot
   Type msconfig in the Run dialog (Win + R). Under the Services tab, check ‘Hide all Microsoft services’ and disable remaining services. Restart your PC and see if the error persists.
8. Reset or Repair Windows
   If none of the above steps work, consider using the Reset this PC feature (Settings > System > Recovery) or performing a repair install with Windows 11 installation media.
