Windows 10 Fingerprint Reader Not Working: Restoring Windows Hello Fingerprint Sign-In
You rest a finger on the sensor and nothing happens, or Windows says it could not recognise you. A Windows 10 fingerprint reader not working forces a return to typing a PIN judolbet88 each time.
Fingerprint sign-in is part of Windows Hello. It depends on the sensor, its driver, a background biometric service, and the stored fingerprint data.
Updates often replace the sensor’s driver, which is why the feature tends to stop after one. Windows may even report that it “couldn’t find a fingerprint scanner compatible with Windows Hello.”
The fault can affect built-in laptop sensors and separate USB fingerprint readers alike, and it often arrives together with a notice that Windows Hello sign-in options are currently unavailable.
Possible Causes
Fingerprint sign-in fails for these reasons:
- The sensor’s driver was replaced, disabled, or is outdated.
- The stored fingerprint data is corrupted.
- Windows has switched the sensor off to save power.
- The sensor or the finger is dirty, damp, or scratched.
Dry or cracked skin in winter is a real cause of poor recognition.
Quick Fixes to Try First
Check the simple things.
- Clean the sensor with a soft, dry cloth, and make sure your finger is clean and dry.
- Restart the PC and try again.
- Sign in with your PIN and open Settings > Accounts > Sign-in options.
- Select Windows Hello Fingerprint, choose Remove, then Set up, and register the finger again.
- Register the same finger twice, and add a second finger as a spare.
Enrolling again resolves most recognition problems.
Advanced Steps for Stubborn Cases
Repair the driver and service.
- Open Device Manager and expand Biometric devices. If the sensor has a warning icon or is missing, select Action > Scan for hardware changes.
- Right-click the sensor, choose Uninstall device, tick the option to delete the driver, and restart.
- Install the fingerprint driver for your model from the laptop manufacturer’s support page.
- In the sensor’s Power Management tab, untick “Allow the computer to turn off this device to save power.”
- Press Windows + R, run services.msc, and set Windows Biometric Service to Automatic, then start it.
If the fingerprint option is greyed out, set up a PIN first, since Windows Hello requires one as a backup.
Before You Go Further: Keep Your Files Safe
Always keep a PIN or password you can remember, because biometric sign-in can fail without warning. Use only the manufacturer’s driver for the sensor. Do not use liquids or sharp tools to clean the sensor surface.
Conclusion
A fingerprint reader that stops responding usually needs its driver refreshed or the fingerprints registered again. Clean the sensor, re-enrol, and reinstall the manufacturer’s driver if the device is missing.
