STOP 0x00000051
REGISTRY_ERROR
Windows hit a fatal error reading or writing the registry — often the registry files on disk are damaged, or the disk underneath is failing.
Likely causes, most common first
- Registry file corruption after a bad shutdown
- A failing disk
- Registry "cleaner" utilities
How to fix it
1. Repair system files and check the disk easy
- Run: sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth from an admin terminal.
- Run: chkdsk C: /f
- Uninstall any registry cleaner utilities.
- If it persists, use System Restore to a point before the crashes.
