On one hand, Drew is right that if it works with 21.X and 22.X, it
should work with 23.X+.

On the other hand, Lennart's right that Alt-Tab is reserved and, to
make it work reliably it would be necessary to write a low level
keyboard hook.

On the third hand, alt-tab role in Vista and Windows 7 is enhanced and
it does not make much sense to try to bypass it and go against the
system (not that it does not make any sense, just not worth the effort
IMHO). So I'm closing this one.

emacs -Q
M-: (w32-register-hot-key [M-tab])
 
Visit a buffer in emacs-lisp-mode.
Type `forward-', then hit `M-TAB'.
 
The Windows TAB dialog comes up (dunno what you call it - a seqence of
icons; you TAB to cycle among their apps) when you hold down the keys
and then disappears when you release them. It should not not come up
at all; instead, `lisp-complete-symbol' should be executed.
 
However, from then on it works as it should. It is only the first time
you press `M-TAB' that Windows doesn't pass the chord to Emacs.
 
emacs -Q
M-: (w32-register-hot-key [M-tab])
 
Visit a buffer in emacs-lisp-mode.  `C-h k M-TAB'. Same as above: the
Windows TAB dialog comes up and then disappears when you release the
keys. And from then on it works OK.
 
In sum, after evalling (w32-register-hot-key [M-tab]) the first
`M-TAB' should be seen by Emacs, but it is not. Only subsequent
`M-TAB's are seen by Emacs.
 
This worked perfectly in Emacs 20 and 21. It is broken starting with
Emacs 22.
