I think a clever developer thought it would be an optimization and hard
coded it. We all need to bombard MS with feedback, I know I did!

It looks like its using the HKCU\Remote\{session id}\Control =
Panel\Desktop
key (which can't be modified) instead of the HKCU\Control Panel\Desktop =
key.
Plus the settings under "Remote\{session id}" looks to be hard-coded
somewhere other than the registry.
What gives?

Ron, Claudio, and I will all be attending the MVP Conference in Redmond =
in
about three weeks. We'll be sure to ask the developers then.
Hopefully that's not too long of a wait!
