Solution Steps
- 1 Run a full antivirus scan: Open Windows Security (Win+I → Privacy & Security → Windows Security) and run a full scan. Malware can corrupt access tokens, so removing it is crucial.
- 2 Run System File Checker: Open Command Prompt as admin and type 'sfc /scannow'. This repairs corrupted system files, including security-related ones.
- 3 Run DISM tool: Type 'DISM /Online /Cleanup-Image /RestoreHealth' to repair the system image.
- 4 Check for Windows updates: Go to Settings → Windows Update and install any pending updates. Updates often include security fixes.
- 5 Perform a clean boot: Type 'msconfig' in the Run dialog (Win+R), go to the 'Services' tab, check 'Hide all Microsoft services', then click 'Disable all'. Go to the 'Startup' tab and click 'Open Task Manager', disable all startup items, and restart. This helps identify if a third-party service is causing the issue.
- 6 If the error persists, use System Restore: Type 'rstrui' in the Run dialog and restore to a point before the error started.
- 7 If all else fails, consider resetting your PC: Go to Settings → System → Recovery → Reset PC. Choose 'Keep my files' to preserve your data.
