Totally sabotaging solution!
My native language has no adequate translation for windows administration tools and most aps. Moreover, I work in Japan and my default input Language is Japanese. Just because Japanese input totally repeats English Input, why would anybody install both here?
So, why the hell do I get my national language in aps instead of English, which is my "DEFAULT INTERFACE LANGUAGE" in locales?
Who was that idiot, who offered ignoring specially implemented localesfeatures?
Now, In windows 10, they changed interface language linking from "Location" to "Default keyboard".
WHAT! WTF! WHY! AGAIN!
I have 3 keyboards installed, neither one is English, because Latin letters are always present in any language I use.
SO, why the hell it gives me JAPANESE in aps, when I have specifically installed English interface everywhere I can!?
I fall back to Windows XP. Or at least to Win7, it was the last "sane" version of windows.
