Yes, but at least GetWindowWord warns when discarding high bytes of the 
instance handle. Besides, this code probably won't compile on a 64-bit 
build anyway.
I did replace some GetWindowLongA calls with GetWindowLongPtrW, but 
there is really no difference between the two A and W versions in terms 
of performance anyway.
