Did you even read my post? The key on his laptop is not in use, that is not how manufacturers activate the laptops. It is such a big misconception for most people, especially on these forums. Believe what you want, but I know the key WILL work because the key IS NOT in use for his laptop.
Scaryjam is accurate regarding vista and seven OEM keys can be applied to any disc retail or OEM on any PC. With XP you'd need an OEM disc paired with an OEM key. Manufacturers don't enable your Windows copy using the same key they place on the case—it requires a master product key.
I'm combining elements now. Keys aren't stored on CDs or DVDs anymore, especially since XP. I don't know much about Win7 OEMs, but my friend @GoodBytes might help clarify. Retail keys and generic OEMs can be used again. Just avoid entering the key while installing. You can re-activate later—if it fails, you have 30 days to obtain a new one.
You can typically use either OEM or retail discs with an OEM key. On average, I activate about 10 Windows 7 PCs per day, and the same disc works regardless of the key type I employ.
