[h-e-w] MS Windows Keybinding

[Will]

Hallo,

how can I delete the default MS Windows Keybinding ALT + LEFT SHIFT 
which switches between us-american and european keyboard settings?

I often use ALT + LEFT SHIFT + ... keybindings and I sometimes 
unintentionally change the keyboard layout which irritates me.

Maybe such a solution can be integrated in the Emacs W32-package?

Thanks in advance,

Will
