title: How can I use `wmic` in a Windows PE script?
body: <p>I'm trying to determine the computer model (e.g., "Optiplex 9010") in a batch script running in the context of Windows PE 3.1.  When running Windows proper, I can do this using <code>wmic csproduct</code> or <code>wmic bios</code> but neither of these return any data when running Windows PE.  (This also seems to be true of most or all other classes.)</p>
  
  <p>I've already installed the <code>winpe-wmi.cab</code> package to support WMI.  Using <code>wmic path</code> instead of an alias makes no difference.</p>
  
  <p>How can I make my <code>wmic</code> commands work?</p>
