The Fast User Switching feature of the Windows

is also supported. If user A is logged on and the fingerprint utility
verifies the fingerprint of user B (who is already enrolled), the
utility recognizes the fingerprint and switches the users.
If your system supports power-on security, existing fingerprint
samples can be used also for power-on authentication.
