Hmmm, this doesn't sound like a great fix.  It's really a "failsafe", but not 
what Windows users expect.  When you open the file again, how will you know that there's

program?  Or you're editing source code / script and then make / run it, nothing will 
tell you about the auto-saved file.

Perhaps better is to have emacs simply abort a restart / shutdown and require 
the user to manually close emacs.  If it doesn't behave like other windows 
programs (query user to save unsaved files), then we have to remember emacs is 
special.  You could have a parameter for whether emacs aborts a windows 
shutdown, default to yes, and then users and consciously shut it off if they 

I'm not convinced that this is better. But as an experiment, I decided to see if I could make emacs do what you want by having a system shutdown trigger 'save-buffers-kill-emacs' instead of 'kill-emacs'. What happened was that Windows complained that emacs was preventing it from shutting down, and it gave me the choice of shutting down anyway or canceling the shutdown. I chose the latter, at which point I was faced with a non-responsive emacs that had to be killed.

I don't have any further ideas.
