Lock your PC with a USB flash drive

PREDATOR is freeware utility that locks your PC when you are away, even if your Windows session is still opened. It uses a regular USB flash drive as an access control device. When you leave your PC you just take your USB drive with you and Predator will lock your PC. While you are away Predator records all security-related events in a log file. By reading this log, you will know if intruders have tried to use your computer while you have been away. When you return back to your PC, you put the USB flash drive in place and your PC will be unlocked.

It's easier and faster than closing your Windows session, since you do not have to retype your password when you return.
