can't access my fingerprint

Question

Why is my Windows Hello fingerprint function 'unavailable'?

Answer 1

Dear Ram Panguluri, 

I understand this can be inconvenient, especially when you are trying to sign in more easily and securely, at this point, I recommend reviewing the responses already posted on your thread. The AI-generated answer outlines several checks that may help address the issue, while the Independent Advisor’s reply includes questions intended to better narrow down the root cause. Those replies typically include the most relevant checks for this scenario.

To help narrow this down further, could you please share a few details: 

• What is the exact device model, and is the fingerprint reader built in or external? 
• Did the fingerprint sign-in work before on this device, or has it never been available? 
• Are you using a built-in fingerprint reader or an external fingerprint device? 
• Do you see any error message under Settings > Accounts > Sign-in options > Windows Hello Fingerprint, or does it only show Unavailable? 
• Is Windows Hello PIN available and working on the same device? 
• Have there been any recent changes on the PC, such as a Windows update, driver update, BIOS change, or hardware change? 
• Does the fingerprint device appear in Device Manager under Biometric devices, or is it missing there? 

In the meantime, here are additional steps that you can try: 

1. Install all pending Windows updates 

• Please go to: Settings > Update & Security > Windows Update > Check for updates 
• Then also review any Optional updates that are offered, install them, and restart the PC. 

2. Confirm the device supports Windows Hello fingerprint and check firmware settings 

• Please verify the exact device model on the manufacturer’s support page and confirm that it supports Windows Hello fingerprint. Microsoft and OEM guidance both indicate that Hello sign-in options depend on the required hardware being present, and device-specific setup can vary by model.  

3. Repair Windows system files 

• Please open Command Prompt as Administrator, then run these commands one at a time: DISM.exe /Online /Cleanup-Image /RestoreHealth and sfc /scannow 
• After both scans finish, restart the PC and check Settings > Accounts > Sign-in options again. 

4. Test in a clean boot environment 

• Press Windows + R, type msconfig, and press Enter 
• On the Services tab, check Hide all Microsoft services 
• Select Disable all 
• Go to the Startup tab and choose Open Task Manager 
• Disable each Enabled startup item 
• Restart the PC and check again.

While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding. 

I hope these steps help restore the Windows Hello fingerprint option on your device and make sign-in available again. Wishing you a smooth experience with your Windows 10 device and successful results with the checks above.

Windows Hello Fingerprint can show as unavailable when the fingerprint sensor, its driver, or the Windows Hello configuration is not working correctly. Use the following steps on Windows 10 to restore it:

1. Clean and check the fingerprint reader
   • Make sure the fingerprint reader (or Fingerprint Power Button) is clean and dry.
   • Use a lint‑free cloth to remove dirt or oil.
   • Do not use glass cleaner or chemicals on the sensor.
2. Verify finger and usage
   • Use the same finger that was originally enrolled.
   • Make sure the finger is clean and dry.
   • Place the finger flat in the middle of the sensor with light, steady pressure and avoid moving it while it is being read.
   • If the finger has scars or damage, enroll and use a different finger.
3. Sign in with PIN or password and re-enroll fingerprint
   • Sign in using PIN or password instead of fingerprint.
   • Go to Start > Settings > Accounts > Sign-in options.
   • Under Windows Hello Fingerprint (or Fingerprint recognition (Windows Hello)):
     • First try Add another and enroll the same or a different finger, slightly changing finger position during setup so more of the fingerprint is captured.
     • If fingerprint is still unreliable or unavailable, choose Remove, then select Set up and configure Windows Hello Fingerprint again from scratch.
4. Check for driver issues and reinstall the fingerprint driver
   • Open Device Manager.
   • Confirm the fingerprint sensor appears under Biometric devices.
   • Right‑click the fingerprint device and select Uninstall device.
   • Restart the PC so Windows can reinstall the driver automatically.
   • After restart, go back to Settings > Accounts > Sign-in options and set up fingerprint again.
5. Reset PIN and biometric service (if fingerprint/PIN both fail)
   • If PIN also fails, sign in with password.
   • Go to Start > Settings > Accounts > Sign-in options > Windows Hello PIN and select I forgot my PIN to reset it.
   • After PIN is working, remove and re‑enroll fingerprint as above.
6. Check Windows Hello Enhanced Sign-in Security components (if applicable)
   • Open System Information > System Summary and confirm Virtualization Based Security is listed as Running.
   • In System Information > Software Environment > Running Tasks, verify bioiso.exe and ngciso.exe are running.
   • If biometrics still do not work:
     1. Remove the existing Windows Hello Face/Fingerprint enrollment in Settings > Sign-in options and re‑enroll.
     2. Reinstall the biometric driver in Device Manager as described above.
     3. Remove the PIN in Sign-in options, then open an elevated Command Prompt and run:

                net stop wbiosrvc && net start wbiosrvc
        

        Then add the PIN again and re‑enroll fingerprint.
7. If it used to work and suddenly stopped
   • A recently installed app, driver, or update might be the cause.
   • Consider a restore or reset of the PC if all other steps fail, after backing up important data.

If none of these steps restore availability of Windows Hello Fingerprint, submit feedback via Feedback Hub and/or contact device support, as there may be a hardware issue with the sensor.
