Predator: Lock, protect, unlock your Windows PC using a USB Drive

Predator is a freeware utility which turns any USB flash drive into a key, with which you can lock & unlock your Windows computer. We have already see how we can use the built-in SysKey Utility in Windows 10/8/7, to lock the computer using a USB stick. Today, let’s check out freeware Predator.

Lock Windows PC using USB

Lock, protect, unlock your Windows PC using a USB Drive

Predator locks your PC when you are away, even if your Windows session is still open. It uses a regular USB flash drive as an access control device, and works as follows:

  1. You insert the USB drive
  2. You run PREDATOR (autostart with Windows is possible)
  3. You do your work.
  4. When you’re away from your PC, you simply remove the USB drive: Once it is removed, the keyboard and mouse are disabled and the screen darkens
  5. When you return back to your PC, you put the USB flash drive in place: Keyboard and mouse are immediately released, and the display is restored.

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

The free version offers the following features:

  • Monitoring options
  • Alarm options
  • Password options
  • Language selection
  • AutoStart with Windows
  • Check for updates
  • Enable Pause.

    Couldn’t get it to work on Win 7 HP 64-bit can anyone tell me if this is an isolated case? Or if the software is only compatible with Win 7 32-bit

    Its because Microsoft has not yet published
    an update of the .Net Frameworks 3.5 for windows 7 64-bit yet.

    Richard Goutorbe the maker of Predator is currently working on this problem, and he hopes to find a solution soon.
