i need to activate the option "Let me set a different input method for each app Windows" on several pcs, but it seems that i can do so only manually...
( "advanced keyboard settings" in windows setting)

i came across several solutions to this problem,
but none of them seem to work properly, without the checkbox being manually marked.
is there a way to enable this option via script or some other registry key? (preferably from a batch script / .reg file - *a test workstation has been restarted in between tries.)
