Resets the Windows Biometric Database by stopping the Windows Biometric Service, deleting all .dat files from C:\Windows\System32\WinBioDatabase, and restarting the service. This resolves fingerprint and facial recognition enrollment issues where biometric data has become corrupted or needs to be re-enrolled.
- Stops the Windows Biometric Service (
WbioSrvc) safely - Confirms the service is fully stopped before proceeding
- Removes all
.datbiometric database files - Restarts the service and verifies it's running
- Color-coded status output with error handling at each step
- PowerShell 5.1 or later
- Must be run as Administrator (stops system services and deletes system files)
- Windows 10/11
This script has no parameters.
.\Remove-BioDB.ps1Stops the biometric service, clears all .dat files, and restarts the service.
