I don't understand the connection here between reusing a running 
instance of Emacs, and integrating with Windows using the registry. 
Anyway, you found the answer to your question - use gnuserv/gnuclient.

set the environment variable EDITOR or VISUAL to gnuclient.exe (or 
gnuclientw.exe depending on the behaviour you want) instead of emacs.exe.

So "emacs --help" would seem to be an obvious thing to try then.
