title: PowerShell $PSVersionTable
body: <p>I have PowerShell 3.0 installed, and I wish to emulate v1.0</p>
  
  <p>When I launch PowerShell 3.0 with -Version 1  $PSVersionTable reports:  </p>
  
  <p>Name                           Value<br>
  ----                           -----<br>
  CLRVersion                     2.0.50727.5456<br>
  BuildVersion                   6.1.7601.17514<br>
  PSVersion                      2.0<br>
  WSManStackVersion              2.0<br>
  PSCompatibleVersions           {1.0, 2.0}<br>
  SerializationVersion           1.1.0.1<br>
  PSRemotingProtocolVersion      2.1  </p>
  
  <p>If I use the -Version 2 parameter I get the same result<br>
  If I use the -Version 3 parameter I get version 3.  </p>
  
  <p>Question, why can't I emulate version 1?</p>
