Force remove keyboard/ language in Windows 10

With Win10 Build 17134 forced onto me, probably about a couple of weeks ago, there is a mysterious “English (United Kingdom)” being added to my keyboard list without my authorisation, and cannot be removed (“remove” button is grey out)! And I decided to unleash my thunderbolt on it using a method I found from below:

Copied here, and thanks to Devlin Sco, in case this will be removed for any funny reason

If you’re unable to remove an input method from Settings, you can use the Windows PowerShell instead. You need administrative permission to perform this advanced system operation.

1. Select the Start button and then type Windows PowerShell.
2. Right-click Windows PowerShell and choose Run as administrator.
3. If prompted, click Yes or enter the administrator password.
4. In the Windows PowerShell window, type or copy/paste each command below and then hit Enter.
   • Get-WinUserLanguageList
     • Take note of the LanguageTag of English – UK.
   • $LangList = Get-WinUserLanguageList
   • $MarkedLang = $LangList | where LanguageTag -eq “<language code>“
     • Replace <language code> with the LanguageTag of English – UK.
   • $LangList.Remove($MarkedLang)
   • Set-WinUserLanguageList $LangList -Force
5. Close Windows PowerShell.
