Set the region format setting to "Match Windows display language" programmatically

I'm looking for a way to set this option by using a batch or PS script. While adding a new language to the registry key is super easy REG ADD "HKCU\Control Panel\International" /t REG_SZ /v LocaleName /d en-EN /f I didn't find any references on how to set the key to match the display language. I assume that this is a Windows Feature only and not bound to a key.

So do I really need to read out the Display Language Key reg query "HKLM\SYSTEM\CurrentControlSet\Control\MUI\UILanguages" first or is my assumption wrong and their really is a universal key to set it to the display language?

Solution

  • I do not know if there is a Registry key for that, but there is a Powershell cmdlet to change it.

    Set-WinCultureFromLanguageListOptOut 0

    Sets it to "Match Windows Display language (recommended)".
    This is also the Default.

    Set-WinCultureFromLanguageListOptOut 1

    Sets it to what ever language you have currently enabled, e.g. English (United States).
