Fix FileCoAuth.exe Application Error in Windows 10 and 11

If you’re experiencing errors related to the FileCoAuth.exe application on Windows 10 or 11, you’re not alone. This error can disrupt your system’s normal operation, especially affecting Windows authentication processes. Fortunately, with a few targeted troubleshooting steps, you can resolve this issue and restore smooth functionality to your computer. Before proceeding, ensure your system is backed up or create a restore point to prevent data loss during troubleshooting.

What You’ll Need

  • Administrator access to your Windows account
  • Stable internet connection
  • Basic familiarity with Windows Settings and Task Manager
  • Optional: Windows Repair or System File Checker tools

Step-by-Step

  1. Identify the Error: First, observe when the error appears. Is it during startup, when opening specific apps, or randomly? Note any error messages or codes, as these can help pinpoint the cause.
  2. Run a Malware Scan: Malicious software can cause application errors. Use Windows Defender or a reputable third-party antivirus to perform a full system scan. Remove any threats detected.
  3. Update Windows: Ensure your Windows 10/11 is up to date. Go to Settings > Update & Security > Windows Update, and click ‘Check for updates.’ Install all available updates and restart your PC.
  4. End the FileCoAuth.exe Process: Open Task Manager (Ctrl + Shift + Esc). Under the ‘Processes’ tab, locate FileCoAuth.exe. Right-click and select ‘End task.’ This stops the process temporarily.
  5. Disable Related Services: Press Windows + R, type ‘services.msc’, and press Enter. Locate ‘Windows Biometric Service’ and ‘Windows Hello Face,’ right-click each, and select ‘Stop.’ Set their startup type to ‘Disabled.’
  6. Delete or Rename the FileCoAuth.exe File: Navigate to C:\Windows\SystemApps\ or C:\\Windows\\System32\, locate FileCoAuth.exe. Right-click and choose ‘Rename’ (e.g., add .bak). Be cautious; if unsure, skip this step.
  7. Run System File Checker (SFC): Open Command Prompt as administrator. Type ‘sfc /scannow’ and press Enter. Wait for the scan to complete and follow any prompts to fix corrupted system files.
  8. Perform a Clean Boot: To eliminate conflicts, perform a clean boot. Type ‘msconfig’ in Run (Windows + R), go to the ‘Services’ tab, check ‘Hide all Microsoft services,’ then click ‘Disable all.’ Restart your PC and check if error persists.
  9. Reset Windows Components: If problems continue, consider resetting Windows components via Command Prompt or using Windows Repair tools. This can fix deeper system issues related to application errors.
  10. Reinstall Windows Hello: If the error relates to Windows Hello or biometric services, go to Settings > Accounts > Sign-in options. Remove and re-add biometric sign-in options or reset Windows Hello.
