In my Windows 10 installation, the little language switcher in the task bar is cluttered with keyboard layouts / locale settings I never use:
So I go to language settings to try and remove them -- but there, only the two I actually want appear. The ones I am trying to remove are only listed in the language bar, but not in the settings.
My end goal is to only have German (Swiss), i.e. Deutsch (Schweiz) and English (US), i.e Englisch (Vereinigte Staaten), and to have the US Layout as the default. How do I achieve this?
