You owner's manual should have the procedures for recovering a system back to factory condition. The newer devices seem to be using the Windows 8 Reset option which uses an image normally kept in a Recovery partition. Using that image to reinstall will take the system back to a factory state.
When you make a Recovery Drive, the link Theog gave you, it will copy that image to the flash drive if there is one. If your system uses a special OEM procedure for recovering, you need to follow those and use their recovery media or some media made with some special OEM utility.
