PB Screen Lock

PB Screen Lock quickly locks your computer whenever you remove your enrolled USB flash drive, and then unlocks your computer whenever you re-insert the same device. It lets you use your USB flash drive like a "house key" for your computer. Screen lock does not keep any information on your computer hard disk - all information used by PB Screen Lock is erased when the program exits, either when you log off or when you press the Exit button. Any USB flash drive can be used with Screen Lock. Screen Lock uses the unique serial number of the USB flash drive that is stored inside the device firmware. PB Screen creates a separate Windows "desktop" without any other processes or Windows hooks to jeopardize keeping your screen locked. No special Windows shortcuts are available in this secure desktop. PB Screen Lock pauses your screen save while it has your desktop locked, and then re-enables the screen saver when you unlock your desktop. This is even true for password protected screen savers.
