Turn off Windows 7 Fingerprint logon

You can control the fingerprint capturing options in the control panel: Start -> Control Panel -> Hardware & Sound -> Biometric Devices

You can turn on/off requirements for fingerprints for local (on by default) and domain (off by default) logins or just turn off fingerprints in their entirety.

Click the right mouse button on the "Computer" shortcut on the Desktop and then "Properties".

On the left side, find and click on the "Device Manager". From the list, find and click "Biometric Devices". Double click on "Validity Sensor" and use 'disable'.

Maybe deactivation/uninstalling the Fingerprint Reader in the Hardware Control Panel will work.
