How to remove unknown "language preferences" in language bar? [duplicate]

I've just gone through the hassle of removing qaa-Latn. Hopefully, this will help others and the future me. In the Admin PowerShell, type:

$LanguageList = Get-WinUserLanguageList
$LanguageList.Add("qaa-latn")
Set-WinUserLanguageList $LanguageList -Force

Then go to Settings (Win+I) / Language settings, and just remove QAA-LATN from there:

enter image description here

Or use another PowerShell script:

$LanguageList = Get-WinUserLanguageList
$Language = $LanguageList | where LanguageTag -eq "qaa-Latn"
$LanguageList.Remove($Language)
Set-WinUserLanguageList $LanguageList -Force

Updated, it just happened again after another Windows 10 update. This time I've simply reset the language list to one default language (en-US):

Set-WinUserLanguageList en-US -Force

Updated, if you also want to get rid of unwanted Win10 language packs, here is how.


Go to Language Preference, look for language qaa-Latn, add it and change Keyboard to the German keyboard then save...it will update the registry..afterwards you can delete it and it will disappear
