What else can you use your USB pendrive for, besides as a place to store data? Okay, you can create bootable USB flash drive to install OS (Windows 8, Linux or the latest Windows 10 Technical Preview) or even use it as rescue disk. You can also run portable apps directly (without installation) from your usb drive. But how many of you knew that you can use USB flash drive to lock/unlock your computer?

Introducing USB Raptor – a lightweight yet handy tool that enables you to turn any USB flash drive into a key that can be used to lock and unlock your computer. When you unplug the USB flash drive, your computer will be automatically locked. To unlock your computer, simply insert the flash drive back to the usb port. It’s simple as that.

To use this tool, first you run the USB Raptor.exe file after you have extracted all the contents from the downloaded zip file. In the main window, you are shown with the simplified interface of USB Raptor. You can check Advanced Configuration to see more options. But as for now, let’s stick with the simple ones.
