Question: Is there an official Windows XP registry reference online somewehere? I see there's a reference for [Win 2000](http://technet.microsoft.com/en-us/library/cc974061.aspx) and [Win 2003](http://technet.microsoft.com/en-us/library/cc778196(v=ws.10).aspx) servers on MS technet, but I can't seem to find one for XP. Yes, I know that Win 2000 reference would be good enough (most things will be the same in XP anyway), but if there's an explicit reference for XP, I'd like to take a look at it.

EDIT: I didn't mean API reference. I'm looking for a reference with descriptions of registry keys, possible values, etc.
