Thanks, Lennart. I couldn't figure out how to do the following and I was 
nervous about diddling with the registry anyway:

1. Add the registry key as described above, i.e.

  [HKEY_CLASSES_ROOT\*\shell\openwemacs\command] ;;; I don't understand 
this

2. Set the value of command to the following, adjusting the path as 
necessary:

  C:\emacs-22\emacs\bin\emacsclientw.exe -n "%1"

The fact that this might not work if emacs weren't running wouldn't be a 
problem since emacs is the first thing I start anyway after booting.

What I did in a cmd shell was:

ftype emacs=c:\emacs\bin\emacsclientw.exe -n "%1"

and then

assoc .txt=emacs

and now from regedit I see:

hkey_classes_root > .txt
emacs

but below .txt > shell > open > command

there is still notepad.exe

If for now I am satisfied with having only .txt files automatically 
opened with emacsclient, what other registry surgery do I have to do?
My assigning a value to directly to .txt seems to be short circuiting 
the notepad command.

Anyway it works as long as I do M-x server-start (or put (server-start) 
in .emacs

Thanks again,

Ed
