I have a server it runs windows 7 like a dream, but I must've bought a counterfeit because the key no longer works. The server never came with any COA, as it was a retired military server. So I guess it is customary for them to remove all COA stickers. Which I know they would not have had Windows 7 installed. But the server is an HP and it's a 64 bit system, So should an HP Windows 7 Professional x64 OEM install without a need of a key since it meets the HP and x64 requirements? I paid the full retail price for the last copy for the server so I'm not trying to cheat the system. Last night I ordered a official HP OEM of the OS. Now I'm having doubts it will work.
