title: Issue with English non-US Culture
body: <p>I am able to use <code>Set-Culture</code> (Powershell as Admin) to set the Current Culture to <code>"en-DE"</code> which is English (Germany). However, when I run the different PS commands to view the Current Culture, I am still getting <code>en-US</code>. I checked my Region (Format) and Location as well. </p>
  
  <p>Do I have to change the system locale as well to Germany (German) ? </p>
  
  <p>This is causing an error in an application, because the datetime format is different from en-DE to en-US and causing the date to be read incorrectly. </p>
  
  <p>When I <code>Set-Culture</code> to <code>de-DE</code>, everything appears to be in working order. </p>
  
  <p>I make sure to run Powershell Console as Administrator, <code>Set-Culture</code>, close console. Open Powershell and run <code>Get-Culture</code>, <code>[CultureInfo]::CurrentCulture</code>, <code>[CultureInfo]::CurrentUICulture</code> and a few more to check and and still getting <code>en-US</code></p>
