Microsoft's GUIDs comply with the OSF (Open Software Foundation) DCE (Distributed Computing Environment)'s specifications for UUIDs. CoCreateGuid calls the RPC UuidCreate, which uses the DCE algorithm...

Specifications for the format and algorithms used to generate UUIDs can be found at http://www.camb.opengroup.org/dce/info/ietf-draft.txt
