Powershell: Change language/culture settings for the current session/window.

1 Comment

Hi,

different language settings on your clients causes some administration issues when you are working with times (formats) or group names for example.

The best workaround is to switch to a unique language at the beginning of the script. This must be done at the thread. The following function switches the langauge. Requierment is, of course 🙂 , the language pack is installed.

function Set-PowerShellUICulture {
    param([Parameter(Mandatory=$true)]
          [string]$LanguageName)
 
    process {
        $oCulture = [System.Globalization.CultureInfo]::CreateSpecificCulture($LanguageName)
 
        $oAssembly = [System.Reflection.Assembly]::Load("System.Management.Automation")
        $oType = $oAssembly.GetType("Microsoft.PowerShell.NativeCultureResolver")
        $oField = $oType.GetField("m_uiCulture", [Reflection.BindingFlags]::NonPublic -bor [Reflection.BindingFlags]::Static)
        $oField.SetValue($null, $oCulture)
    }
}

For example: Switch to German:

Set-PowerShellUICulture -LanguageName de-DE

One thought on “Powershell: Change language/culture settings for the current session/window.”

  1. This does not work on PowerShell 7:

    InvalidOperation:
    Line |
    11 | $oField.SetValue($null, $oCulture)
    | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    | You cannot call a method on a null-valued expression.

    Any idea how to fix? Thanks
