(global-set-key [print] 'forward-char)
(w32-register-hot-key [print]) ; => 42

Has no effect: The Print Screen key is still not recognized by Emacs.

Sorry, I don't know what the last clause means.  What w32-* modifier
variables, and how?

But from your and Martin's other replies in this thread it appears that
`w32-register-hot-key' is useless for Windows 7.  Unless I missed
something.  Is there any case at all where it actually will have an
effect?
