[h-e-w] Some problems with keybindings

[germano carella]

Hi to all,

I'm Germano from Italy.
I'm using emacs 25.1.1 on windows 10 64 bit.

I'm trying to map left window key but I've some problems.

I set w32-pass-lwindow-to-system to nil, and w32-lwindow-modifier to 'super.

Some keys are recognized, for example win+f9, win+f10, but win+j is not 
recognized.

There is a way to pass left window key to emacs? Perhaps with 
autohotkey, but I don't know how to do this.

I tried  to register alt-tab with w32-register-hotkey, but it doesn't 
work...

Some suggestions?

Thanks!
