Every PC Technician who comes around a OEM preinstalled garbage Windows and realy knows what he is doing is diskparting the whole hdd and is reinstalling with a genue garbageles original Windows-Medium. The only way to get rid of all the funny settings, crapware and maleware (norton antivir!!) in a timly maner. To mix with the preinstalled garbage Windows with such a "tool" makes it only worse. It's like mixing garbage with garbage and hope to get not a pile of garbage after mixing them together.
