Sound so if I just buy a 32 bit windows 7 from eBay I just bung the disc in, follow some on screen instructions, type in a product key, agree to sell my soul to Microsoft and all the other T's&C's you have to agree to and then wait a bit and BOOM I have windows 7 ???? Sounds too easy to be true... is it really just as easy as installing a game or a new piece of software ie iTunes ???
