OK...

Could this one be done by modifying the existing W32_GETREG to return 
subkeys? ... Hm, I guess that wouldn't since registry entries always 
have a value.

Maybe it's this particular example, but that one seems problematic. Does 
it return the "Data" part, the "Name" part, or both?

I'd think that both of the above could be covered by just adding a 
single new rule W32_GETREG_KEYS to return the names and subkeys of the 
given entry.
