Windows Prof Registry Architecture

I have a question about finding references on the Windows 2000 Prof (or XP) registry. I have references on the layout of the hives, types of values, etc. But, what I’m looking for is something on a deeper level. I’m looking for a reference which shows how the GUIDs of the Type Libraries (HKCR\TypeLib) relate to (HKCR\AppID) and the Type Libraries of (HKCR\Interface\Typelib). What I want to do is to take a GUID and understand what its values in the different parts of the HKCR hive are doing. While I’m at it, I’d also like to know what all the sub-keys under HKCR\…\ mean, such as ProxyStubClsid32. Any suggestions would be appreciated.
