bug#24453: Hyper and super keys don't work in some branches

[Mambo Levis]

This is what "System Information" tells me:
OS Name    Microsoft Windows 10 Home
Version    10.0.14393 Build 14393

Here are all the unshifted keys that got passed through:

s-y is undefined
s-n is undefined
s-[ is undefined
s-] is undefined
s-. is undefined
s-` is undefined
s-- is undefined
s-; is undefined
s-' is undefined
s-\ is undefined

All the other unshifted keys were blocked.

Levis >>> Yes, in my case version 24.5 works like yours. 

My system information

OS: Microsoft Windows 10 Pro N

Version: 10.0.10586 Build: 10586

My problem is in the version 25.1 release where the super key don't work at all, I check all combinations and none of them work.

s-a, 

s-b, 

s-c, ..., s-z, 

s->, 

s-< 

etc 

Please notice that these combinations work:

C-s-a is undefined

C-s-b is undefined

C-s-c is undefined

etc 

All of the work!

Let me understand what exactly is the nature of the problem: is it
true that only _some_ hyper- and super- key combinations don't work?
Or do none of them work in Emacs 25.1?

Levis >> None of them work in Emacs 25.1 official release. For example, key combinations starting with super don't work, but if I make a combination

such C-super-a (C-s-a) works. It seams that super and hyper can't be triggered as prefix.

No suggestions.  If setting w32-use-fallback-wm-chars-method to a
non-nil value doesn't help, I don't know how this is possible, since
there's no other difference between Emacs 24.5 and 25.1 I know about
regarding keyboard support.

Let me understand what exactly is the nature of the problem: is it
true that only _some_ hyper- and super- key combinations don't work?
Or do none of them work in Emacs 25.1?
