What other w32 apps are you talking about? The Windows programming 
guidelines are pretty clear that the only time to interrupt shutdown is 
when you are performing an operation that cannot be interrupted - CD 
burning is given as an example. In that case you are supposed to ask the 
user one Yes/No question about whether they want to abort the shutdown.

As I said at the start of the thread, it would be correct for Emacs to 
flush its autosave buffers to disk at this point, but not to start 
asking all the questions that save-buffers-kill-emacs does. What if 
Emacs is on a secondary monitor, and the Graphics driver shuts it off 
when it receives the shutdown message? Emacs will be delaying shutdown 
waiting for a response, while the user cannot see it.
