Lock the option to change system language while cubase in focus

an option or permanent lock of changing languages in windows with (shift+alt) while using cubase.(i know its possible to change the Shift+alt in windows but again its gonna set new key modifier conflicts)
many key commands in cubase are assigned using the modifier keys, and it changes windows language (for those who use more then one language in their computer) and its lead to confusion, mistakes and also key commands not functioning as intended in cubase itself.
im using also protools, and there when protools is in focus you cant change the system language with modifiers(shift+alt) so no KC mess-ups there
so the bottom line of my request .
when cubase is in focus,dont let the key modifiers change the language of the system. we can change the language if needed while using cubase with the mouse
