I’m from Eastern EU but work in Germany in English. As I grew up with my native language’s keyboard, I always set that up, but turn the display language to English.
Worked fine in 10, but with the new 11 work laptops most things are indeed English, some apps are in my native language, and some in German. And a few days ago, lock screen stock photos started appearing (instead of the company’s logo as before), with quotes in my native language. All because I want to use a specific keyboard.
Based on searching, this is a known problem, win 11 languages are a mess, and no way to fix without resetting settings and reinstalling some things, for which I would need to leave my computer with corpo IT.
