I guess so - that's what I see, at least.

But what's important here is what happens after that.  If you use `M-TAB' in
Emacs.  E.g, if you type, say, `forward-w M-TAB' in the *scratch* buffer then
Emacs should complete that to `forward-word'.

You might have to try using `M-TAB' twice.  It seems that the first time I use
it Emacs does not capture it, but thereafter it does.

If you want `M-TAB' from within Emacs to go to Windows and not to Emacs then
don't use `w32-register-hot-key' as I suggested.  It depends what you want.

Maybe; dunno.  I'm on XP.

I believe it's supposed to work on Windows in general.  If it does not, consider
reporting a bug: `M-x report-emacs-bug'.
