OK, I found it:
It is in LOCAL_MACHINE > System
Each registrated user "CurrentControl" has an own "Enum" folder with different hardware sets in it.
These have subordinated folders for different information. Unformtunately it just goes for ALL PCI, PnP or ISAPnP devices. <_<
Ah, what the hell, it's my home test system so I'll give it a try. Otherwise I'll have coffee and set it up anew.
Once more... *sigh* But these are the most valuable IT-experiences. In my opinion.
