You will first need to go to the manufacturers website for your model computer and first find out if there are Windows 7 native drivers available. A lot of computers that come preloaded with Windows 8 do not have native driver support for Windows 7 by the manufacturer. If there are no native drivers, you will have to consider returning the machine and purchasing a machine preloaded with Windows 8 Pro with downgrade rights to Windows 7 Professional. Or look through the manufacturers catalogue for systems already preloaded with Windows 7, usually the business line will have these options.
