How to Install a Keyboard Without a Language Pack in Windows 10
Go back to the language screen by clicking on Start > Settings > Time and Language > Region and Language.
Highlight the language pack that you want to associate your new keyboard with and click Options. Next, click Add a New Keyboard and make your choice from the list.
You can also remove keyboards from this menu; useful if you want to change your system language to Spanish, but want the only keyboard to be English QUERTY. Just highlight the keyboard you want to delete and click Remove.
