Does Windows 8.1 ignore its primary language setting?

Since a few days, when I close and reopen Notepad++, it's input language is Dutch. I want this to be English unless I manually change it (which I rarely do). I do want to have Dutch available for these rare occasions.

I looked into my language settings and what I understand is that English is my "primary language". Is this setting erroneously ignored or do I need a different setting?

Note that things were working fine but then this problem suddenly appeared out of nowhere..

Solution 1:

Examine further possible adjustment under Advanced settings; among others, next settings are important:

  • Override for Windows display language: keep the default Use language list (recommended) option selected for this list;
  • Override for default input method: change from default Use language list (recommended) to desired input method which any newly launched app window should start with; in your case it could be probably
    • English (United States) - US or
    • English (United States) - United States - International;
  • Switching input method:
    • Let me set a different input method for each app window checkbox: if unchecked, changes previously adjusted default input method to recently selected one all windows-wide.

FYI, here are my own advanced language settings (with Czech instead of Nederland): enter image description here
