So I needed to re-install Windows 7 HP x64 on a customer's computer, and stupid me forgot to retrieve the CD key before doing so. Now, the CD key put in there is getting told it's invalid, and Windows is not genuine. I have access to the Inplace Upgrade folder and the old Windows folder, but the SOFTWARE registry key looks to be missing, so I can't seem to use a keyfinder. Is there something I'm missing here, or do I need to shell out some money for another key?

In the old Windows\System32\config folder, it has the hives there but they're in a TSF format, which I've never seen, so key finders don't seem to want to work on it. Also @Ranon, I believe you're right. There's a Vista sticker on it, and he had a genuine copy of 7 before cause he was running MSE – Canadian Luke Oct 27 '11 at 18:15

Was this system originally Windows 7 from HP? If so you can order a recovery disc set, then you don't need a key, it will install one automatically during… – Moab Oct 27 '11 at 20:34
