Latitude fingerprint driver on Windows 8

Hi,

I installed Windows 8.1 on my Dell Latitude E6520. I want to know how can I find the driver for my fingerprint ? Windows 8 doesn't find my fingerprint on "sign in options" page but on "device manager" I have "Dell ControlVault w/ Fingerprint Swipe Sensor" valid.

I have to install the heavy soft Dell Control Vault like I did on Windows 7 ? I really prefer let Windows 8 manage my fingerprints.

Thanks
