Windows 10 April 2018 Update added an extra Language and I cannot remove it

Question

I have just updated to Windows 10 April 2018 Update (1803 / 17134.1)

I had my laptop configured completely as UK with only a UK keyboard layout

Since the update, a US keyboard has been added so I now see the switch icon in my task bar

It appears that all the keyboard language settings are now migrated to the new Settings app and no longer in the old Control Panel

However, as can be seen from the screenshot above, the Remove button under the newly added US layout is greyed out (as is the UK one)

How can I remove the US layout?

UPDATE 1: I just updated my desktop and it hasn't added a US keyboard!

UPDATE 2: I added a third language (French) and was able to remove it, the button was enabled. The US remove button remained disabled both after adding French and after removing it.

UPDATE 3: I added another English language (Australian) and this cannot be removed! Button is disabled

UPDATE 4: I followed this answer except I removed the values from the keys for all users and also the values under the Substitutions key. The task bar switch icon is gone but I still have all 3 languages in Settings still

Answer 1

Finally found a solution using PowerShell.

You can view your language list with Get-WinUserLanguageList

$1 = New-WinUserLanguageList en-US
Set-WinUserLanguageList $1

now you can check again your new language list with Get-WinUserLanguageList Logoff, Reboot. After rebooting you can add another languages if needed.

Answer 2

Just trying to improve naduvko's answer.

You can directly specify the entire list of languages when running the PowerShell script.

Like this:

$1=New-WinUserLanguageList en-US
$1.Add("nl-NL")
$1.Add("de-DE")
Set-WinUserLanguageList $1

The first one (en-US in this example) will be the default.

Adjust as needed.

(Yes, it's ridiculous that we need to program PowerShell to modify the fricken input languages)

Answer 3

On my Windows (Version 10.0.16299.371) I have a Set as default button that seems to be replaced with the arrows in your interface. Try to make the UK the default. That would unlock US for removal.
