type and does a lot of corrections ( in the German sense ).
You can change this only by changing the whole windows settings.

The solving hint was this answer:
I had same problem.
Just set up 3 different keyboard, go control panel -> language (i use view by small icons) -> add language -> find your language -> then option on that language -> there click "add an input method" and choose your native keyboard layout (don't forgot remove native layout for that language ) That's it. You can change language correction just by hitting win key + spacebar and autocorrection will change but your native layout will stay ^_^
enjoy the day!
