There is a refresh option built in to all Windows 8 PC's which allows them to be reset to factory condition without the need for additional recovery media.
To do this, go to the start screen and type "recovery" and click the result "Recovery Options" which will take you to the metro-CP. Here you can choose to "refresh" which essentially keeps your personal files but will remove all your programs and apps, or you can choose to remove everything and start "fresh". This should also exclude all of the crapware that comes preinstalled on PC's.
