How to Fix Windows Hello Not Working

Resolve Windows Hello authentication errors with these precise steps to reset biometrics, update drivers, and reconfigure your sign-in options.

1. Check for system updates. Open Settings by pressing Windows + I. Navigate to Windows Update and click Check for updates to ensure your security patches and biometric drivers are current.
2. Reset Windows Hello biometrics. Open File Explorer and navigate to C:\Windows\System32\WinBioDatabase. Delete the contents of this folder to clear existing biometric data. This forces Windows to create a fresh identity profile upon the next setup.
3. Reinstall biometric drivers. Right-click the Start button and select Device Manager. Expand Biometric devices, right-click your sensor (e.g., Windows Hello Face or Fingerprint), and select Uninstall device. Restart your computer to trigger an automatic driver reinstallation.
4. Re-enable sign-in options. Navigate to Settings > Accounts > Sign-in options. Locate your preferred method, click Remove, and then click Set up to register your face or fingerprint again from scratch.
5. Repair system files. Press Windows + S, type cmd, and select Run as administrator. Execute sfc /scannow and press Enter. Allow the tool to repair any corrupted system files that may be interfering with the Windows Hello service.
