Change language to enlish on PC

Good morning Forza Community,

I have a rather simple problem, but can’t seem to find the answer.
I would really like to play Horizon 4 in English (original language) because I don’t really like the voice sync…
But I can’t find the setting to do so.

I looked on the internet and it said I need to add English as a language in Windows and set it as my primary language. This way all of my Apps from the Windows store should be in English. Well, all of them are (Calculator, XBox App, etc) but Horizon 4 just won’t change to English.
Do I have to reinstall it or is there another solution to this?

You have to change the windows region setting, not the language.

I have my region as UK, English (UK) as main language, English (US) as secondary language, and reinstalled the game. The store is in english, the XBox App is in English, but Forza won’t change.
