powershell : changing the culture of current session

As the accepted solution by @manojlds actually doesn't work (PS 5.1 on Windows 10) here what works for me (found on github):

$culture = [System.Globalization.CultureInfo]::CreateSpecificCulture("en-US")
$assembly = [System.Reflection.Assembly]::Load("System.Management.Automation")
$type = $assembly.GetType("Microsoft.PowerShell.NativeCultureResolver")
$field = $type.GetField("m_uiCulture", [Reflection.BindingFlags]::NonPublic -bor [Reflection.BindingFlags]::Static)
$field.SetValue($null, $culture)

Have a look here: http://blogs.msdn.com/b/powershell/archive/2006/04/25/583235.aspx

and here: http://poshcode.org/2226:

function Set-Culture([System.Globalization.CultureInfo] $culture)
{
    [System.Threading.Thread]::CurrentThread.CurrentUICulture = $culture
    [System.Threading.Thread]::CurrentThread.CurrentCulture = $culture
}

Additional Info

To find which values can be used for $culture:

• This will give you a list of Culture Types:

  [Enum]::GetValues([System.Globalization.CultureTypes])
  

• Selecting one of the above types (e.g. AllCultures) you can then list the available values of that type:

  [System.Globalization.CultureInfo]::GetCultures( [System.Globalization.CultureTypes]::AllCultures )
  

• You can then use the Name or Number of the culture you're interested in with the GetCultureInfo method to retrieve the value you're after:

  $culture = [System.Globalization.CultureInfo]::GetCultureInfo(1033)
  $culture = [System.Globalization.CultureInfo]::GetCultureInfo('en-US')
  

NB: Thanks to implicit conversion, you could just pass the culture name or number (i.e. as a string or integer) to the Set-Culture method which would automatically be converted to the expected CultureInfo value.
