i got a message today when i logged in saying i might be using a bootlegged copy of windows 7 and i need to register it again
What name loader? Use a loader or use a tool like RemoveWAT, but don't use both as that's self defeating. Personally I'd recommend a loader because it tinkers less with system files, and Microsoft normally targets modifications to system files in anti-piracy updates. A loader will give problems if it used the blacklisted Lenovo key. You happen to install update KB971033 recently? This is Microsoft's latest anti-piracy update.
