System Restore doesn’t get rid of files that you’ve saved.. System Restore simply reverts to Windows settings as of the restore point. This can help if you or some piece of installed software made a setting that is causing some conflict in your system that makes your computer sluggish or prone to crashes.

System Restore doesn’t always solve the problem. You very best bet is to be sure you create a set of backup discs for your computer when you buy it. If you didn’t do that, and you can’t get things running right again, contact your computer manufacturer. They may be able to send you a set of recovery discs, though they may charge a small fee. These discs restore your computer to its state when it left the factory, and in this case you lose applications you installed and documents you created, but you get your computer running again.
