Thanks! I will try that. In the mean time I found what was preventing me from deleting the registry with regedit32. Turns out that, every time I gave myself permission to a particular VID key, a new sub-node gets created with no permissions. One needs to refresh Reg Editor after each time a permission is added in order to see this. After two or three iterations, it finally stops creating these sub-nodes and one can finally delete the registry. I was logged into the machine from an external domain, not to the machine itself. That may be part of the problem since, I noticed, each new sub-node has <LocalMachine>\Administrators automatically added. Regards.
