Windows GUID listings

I've been looking for a complete listing of important GUIDs the best I can find is http://www.myplugins.info/guids/guidlist.php although it seems like it is still missing some things like the GUID for IContextMenu. Would anyone know how to find thes开发者_StackOverflow社区e? Or is there a better listing of commonly used GUIDs in Windows?

What sort of GUIDs are you looking for? If you're looking for Windows SHELL GUIDs (like the aformentioned IContextMenu), SHLGUID.H from the Windows SDK is a good place to start...
