I want to add a new computer to my office network and was thinking of taking an assembled PC and putting Win 7 on this. Instead of using a pirated one with Daz I was checking if some licenses are available at low cost and it seems online sites in India have the OEM version of Win 7 Pro available for half the price of retail versions. Are these legal? I understand that I cannot transfer this to any other computer. But is this any better than buying an MSDN key from say Reddit for even lesser price or just activating with Daz loader.
