Reinstall Windows 10 Pro (UK) to another system language (US)?

Question

I have a problem. When I bought my Windows 10 Pro, I chose English (international), in that time I don't understood that this option is UK version (I need only US version). I added US language, but I have new problem, I can't remove any of English languages. I try to change this problem use PowerShell I found this solution in superuser.com

But I still see two languages.

Do I need to reinstall my Windows 10 Pro to another system language?
And if I reinstall my Windows 10 Pro, will my license work?

P.S: sorry for my English, I working on it.

If nothing worked, then you can try this:

1. Open regedit.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex\Language
3. Remove English_UK subkey.
