If your biometric sign-in isn't working and you're receiving prompts to use a different finger or adjust your finger position, you can try the following troubleshooting steps:
- Check VBS: Ensure that Virtualization Based Security (VBS) is running. You can verify this by opening System Information and looking for Virtualization Based Security listed as Running.
- Biometric Isolation Trust-lets: Check if the biometric isolation trust-lets are running. They should be listed under System Information > Software Environment > Running Tasks as
bioiso.exeandngciso.exe. - Re-enroll Fingerprint: Go to Settings > Sign-in Options, remove the nonfunctioning fingerprint enrollment, and re-enroll your fingerprint.
- Device Manager: In Device Manager, ensure that your fingerprint sensor is listed under Biometrics devices. If it is, try uninstalling the driver and then restarting your device to allow Windows to reinstall the driver.
- Restart Biometric Service: Remove any existing PIN from the system and restart the biometric service by running the command
net stop wbiosrvc && net start wbiosrvcin an elevated command prompt. - Feedback Hub: If the issue persists, consider filing a feedback item using the Feedback Hub to report the problem.
These steps should help you resolve the issues with biometric sign-in.
