registry monitor

Question

Hi,
Is it possible to write a registry watcher with the .net framework. As far my research have gone seems that monitoring registry is a framework limitation.

One implementation i think it's achievable through enumerating keys and subkeys with retrospective method (snapshot1). After installing a program run again the retrospective method (snapshot2) then compare the two snapshots. 

There is also a very advanced program process monitor but it doesn't give me the functionality i want.
Thanks keep up the good work
