How to Fix Fingerprint Not Working Error on Windows 10: Step-by-Step Solutions

Fingerprint scanners are a convenient way to quickly unlock your Windows 10 device. However, sometimes the fingerprint sensor may stop working, causing frustration. This article will guide you through simple and effective steps to fix the fingerprint not working error on Windows 10.

These solutions are designed to be easy, even if you are not very tech-savvy. By following each step carefully, you can get your fingerprint sensor working again in no time.

No need to worry about complex technical jargon—each fix is explained clearly and logically. Just take your time and try the steps one by one.

Let’s begin with some quick checks before diving into detailed troubleshooting.

Quick Note: What to Check Before You Start

Ensure your Windows 10 is updated: Sometimes, fingerprint issues occur due to outdated system files.
Clean the fingerprint sensor: Dirt or oil on the sensor can prevent it from reading your fingerprint properly.
Make sure your finger is clean and dry: Wet or dirty fingers may not be recognized by the sensor.
Check if other sign-in options work: Ensure that your password or PIN still lets you access your device.

Step 1: Restart Your Computer

Before making any changes, restart your computer. A simple reboot can fix many minor glitches, including fingerprint sensor issues.

Restarting clears temporary files and resets hardware connections, which might solve the problem instantly.

Step 2: Update Windows 10

Keeping Windows updated is important because updates include fixes for hardware and software problems.

To update Windows:

Click the Start menu and select Settings.
Choose Update & Security.
Click on Windows Update from the left menu.
Select Check for updates and install any available updates.

After updating, restart your computer and try the fingerprint sensor again.

Step 3: Re-register Your Fingerprint

If your fingerprint is not recognized, it might help to delete the old fingerprint data and add a new one.

To re-register your fingerprint:

Open Settings from the Start menu.
Click on Accounts.
Go to Sign-in options.
Under Windows Hello Fingerprint, click Remove.
After removing, click Set up to add a new fingerprint.
Follow the on-screen instructions to scan your finger multiple times.

Make sure to scan your finger from different angles for better recognition.

Step 4: Update or Reinstall Fingerprint Driver

The fingerprint sensor relies on drivers to communicate with Windows. If the driver is outdated or corrupted, the sensor may not work.

To update or reinstall the driver:

Right-click on the Start button and select Device Manager.
Expand the Biometric devices section.
Right-click your fingerprint device and select Update driver.
Choose Search automatically for updated driver software.
If no update is found, you can try uninstalling the driver by selecting Uninstall device.
Restart your computer. Windows will attempt to reinstall the driver automatically.

This process helps fix driver-related issues that could be blocking fingerprint functionality.

Step 5: Check Windows Biometric Service

The fingerprint sensor depends on a Windows service called the Biometric Service. If this service is stopped, the sensor will not work.

To verify and start the service:

Press Windows + R keys to open the Run dialog.
Type services.msc and hit Enter.
In the Services window, scroll down and find Windows Biometric Service.
Right-click and select Properties.
Set the Startup type to Automatic.
If the service is stopped, click Start.
Click Apply and OK.

Restart your computer and test the fingerprint sensor again.

Alternative Method: Use Windows Troubleshooter

Windows has a built-in troubleshooter that can detect and fix problems automatically.

To run it:

Open Settings and go to Update & Security.
Select Troubleshoot from the left panel.
Click Additional troubleshooters.
Find and select Hardware and Devices, then click Run the troubleshooter.
Follow the on-screen instructions.

This tool can identify issues that might be missed by manual checks.

Frequently Asked Questions (FAQs)

Why is my fingerprint sensor not detected on Windows 10?

This can happen if the fingerprint driver is missing or outdated, the biometric service is stopped, or the sensor hardware is dirty or damaged.

If you have tried all the above steps and your fingerprint sensor still doesn’t work, consider the following options:

Check hardware warranty: If your device is under warranty, contact the manufacturer for support or repair.
Visit Microsoft Support: Microsoft provides official help for Windows Hello issues at support.microsoft.com.
Use alternative sign-in methods: In the meantime, rely on PIN or password login for device access.
Consider professional repair: If hardware damage is suspected, a certified technician can diagnose and fix the sensor.

Conclusion

Fingerprint sensor issues on Windows 10 can be caused by simple software glitches, outdated drivers, or hardware problems. By following the easy steps outlined here—from restarting your device to updating drivers and checking system services—you can often restore fingerprint functionality without hassle.

Remember to keep your device updated and maintain the sensor clean for the best performance. If problems persist, don’t hesitate to seek professional help or use alternative sign-in methods.
