System Restore is a feature on your computer that takes regular "snapshots" of your computer's settings and programs. It's like taking a picture of the way your computer is set up. If anything goes wrong with your computer, like if you suddenly can't get onto the internet or one of your programs isn't working, you can use System Restore to turn your computer back to how it looked when it worked perfectly. That way, you usually don't have to do anything else to your computer. It's like traveling back in time to when your computer was working correctly!
