I'm looking for the cheapest solution to get a Windows 7 to my netcafe. Personally I use Gnu/Linux but apparently most of people don't. I'm thinking of ordering windows product keys only, to cut the cost from this website.
But I'm afraid that this is illegal site i.e. it sells key-gen made product keys. I thought about getting OEM editions.
Microsoft does not reveal any info about the price of open volume licensing. (I need 8 copies only for now)
