title: Laravel\Symfony Process component fails to start new process
body: <p>I'm using the Process component provided by Symfony in my Laravel project: <a href="http://symfony.com/doc/current/components/process.html" rel="nofollow">http://symfony.com/doc/current/components/process.html</a>. </p>
  
  <p>Here is my code:</p>
  
  <pre><code>$process = new Process('dir');
  try
  {
      $process-&gt;mustRun();
      print $process-&gt;getOutput();
  } catch (ProcessFailedException $e) {
      print $e-&gt;getMessage();
  }
  </code></pre>
  
  <p>So, nothing fancy here, just a cookbook solution. However, I'm getting the following error:</p>
  
  <pre><code>The command "dir" failed.
  Exit Code: 1(General error)
  
  Output:
  ================
  
  
  
  Error Output:
  ================
  </code></pre>
  
  <p>I cannot figure out what's the problem since there is nothing in logs. If it matters, I'm running it on Windows Server 2008 R2.</p>
