You can install security software to keep track of your laptop’s location, should it ever be stolen. One of the best options is a free application called PREY. Here are step-by-step instructions for using it.

1. Go to //www.preyproject.com/
2. Download PREY free and install it
3. Create your account
4. Log in to the PREY Control Panel to set up your alerts and so on

If your laptop does go missing, install PREY on another machine, and click the Missing? tab. You’ll be able to turn on the webcam, lock the PC, password protect it, and even geolocate it, all remotely.
