How to Fix Windows Hello Fingerprint Not Working After Reboot on Windows 11

Rahul Vithala
Windows 11

Fingerprint login works great during your session but sometimes fails to recognize after a reboot. The sensor goes silent or Windows says it can’t recognize your print. This happens more than it should, especially after updates. Power management, driver glitches, or Enhanced Sign-In Security (ESS) are usually behind it. Here’s how to get it working again.

1. Restart Windows Biometric Service

The service sometimes fails to start properly after boot.

  1. Win + R > cmd > Ctrl + Shift + Enter (admin).

  2. Type net stop wbiosrvc && net start wbiosrvc > Enter.

  3. Test fingerprint.

A quick reset works temporarily until the next reboot.

2. Reinstall Fingerprint Driver

Updates often break drivers.

  1. Win + X > Device Manager > Expand Biometric devices.

  2. Right‑click sensor > Uninstall device > Check “Delete driver” if shown.

  3. Restart PC Windows reinstalls automatically.

  4. If needed, download the latest from the laptop maker (Dell/HP/Lenovo sites).

3. Disable Power Management on Sensor

Windows powers off the sensor to save energy, but it won’t wake up.

  1. Device Manager > Biometric devices > Right‑click the sensor > Properties.

  2. Power Management tab > Uncheck Allow the computer to turn off this device.

  3. OK > Restart.

Keeps sensor active post‑reboot.

4. Turn Off Enhanced Sign-In Security (ESS)

ESS requires specific hardware; mismatches block fingerprints after reboots.

  1. Settings > Accounts > Sign-in options > Additional settings.

  2. Toggle Enhanced sign-in security off (if visible).

  3. If grayed out, registry: reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WinBio" /v SupportPeripheralsWithEnhancedSignInSecurity /t REG_DWORD /d 0 /f > Restart.

Re-enroll fingerprints after.

5. Re‑Enroll Fingerprints

Corrupted scans cause recognition fails.

  1. Settings > Accounts > Sign-in options > Fingerprint recognition.

  2. Remove all prints.

  3. Set up new ones (use 2-3 fingers).

  4. Restart and test.

Prevention

  • Update drivers/firmware from manufacturer.

  • Keep ESS off if hardware doesn’t fully support it.

  • Test login after updates.

FAQ

1. Why does the fingerprint work in session but not after reboot?
Power management turns off the sensor, or ESS blocks it until re‑enabled.

2. Does reinstalling the driver fix it?
Often yes—updates corrupt drivers. Use the manufacturer’s site for the latest.

3. What is Enhanced Sign-In Security?
Isolates biometrics in secure hardware; can fail on non‑ESS sensors post‑reboot.

4. How do I restart biometric service?
Admin CMD: net stop wbiosrvc && net start wbiosrvc.

5. When to re-enroll fingerprints?
After driver changes or ESS toggles, old scans get mismatched.
