How to remove Unknown Locale (Keyboard) from the Language Bar

After installing updates, you may find unknown locale(s), such as QAA-Latn or QAC-Latn, when you click the Language bar, as seen in the screenshot below.

However, the QAC and QAA entries do not appear in the list of languages when you open SettingsTime & LanguageLanguage. You wonder how to remove the unknown keyboard languages from the listing.


Using PowerShell, you can remove those unknown keyboard layouts automatically.

  1. Start PowerShell as administrator.
  2. Run the following command:
  3. Press Enter.
    remove unknown locale keyboard from language bar

    (The Get-WinUserLanguageList cmdlet returns the current user language settings. These settings include input method, spelling setting, text prediction setting, and handwriting input mode.)
  4. In this case, you may want to retain en-US and en-IN languages and delete the remaining ones. To do so, run the following command:
    Set-WinUILanguageOverride en-US, en-IN -Force
    Note: To retain only en-US, you’d type “Set-WinUILanguageOverride en-US -Force
  5. Now, click the Language bar to see if the changes are effective.

That’s it! The English (United States) and English (India) entries are retained. The QAA-Latn and QAC-Latn entries are removed.
