How to reset your computer to Factory Settings?

Shut down your computer. You must first shut your computer down to initiate the factory restore.

Start up your computer and as the computer logo appears (such as Dell or HP) hit "Ctrl>F11" simultaneously. This may be different for different machines, but the most common keys to hit are "Ctrl>F11." If this does not work, the F8 key has been said to work for certain machines.

Select "Repair My Computer" from the list of menu options that appear and press "Enter."

Choose the language settings that you would like and then click enter.

Enter the administrator log in and password if it asks you for this information.

Choose the factory reset option. This should reset your computer to the factory settings when you bought your machine.
