i did an update and now my finger print scanner wont work

Try these steps in order:

1. Make sure Windows Hello is still configured, then install the latest Surface or Windows updates.
   • Open the Surface app > expand Help & support > check update status.
   • If updates are available, select Check for updates to open Windows Update and install them.
2. Sign in with a PIN or password instead of fingerprint, then re-register the fingerprint.
   • For Windows 10: Start > Settings > Accounts > Sign-in options > Windows Hello Fingerprint.
   • Select Remove, then select Set up to add the fingerprint again.
   • It can also help to select Add another and register the finger from slightly different positions.
3. Check the finger and sensor.
   • Use the same finger originally enrolled.
   • Make sure the finger is clean and dry.
   • If using a Surface Laptop Go fingerprint power button, place the finger flat in the middle with light pressure and avoid moving it.
   • Wipe the fingerprint reader/power button with a lint-free cloth. Do not use glass cleaner or cleaning chemicals.
   • If the finger has a scar or damage, enroll a different finger.
4. If the update was recent and it worked before, a recent app, driver, or update may be causing the issue.
   • Try Restore or reset your PC.
5. If the device upgraded from Windows 10 to Windows 11 and uses certain ELAN fingerprint drivers, Microsoft has a validated workaround using:
   • sfc /scannow
   • This applies to ELAN fingerprint driver versions 3.10.11001.10606, 3.10.11001.10502, or 3.10.11001.10801 with affected onnxruntime.dll versions.
   • The troubleshooter for this issue runs automatically and cannot be run manually.

If PIN sign-in also fails, reset the PIN:

• Start > Settings > Accounts > Sign-in options > Windows Hello PIN > I forgot my PIN.
