title: cmd /q not working as expected
body: <p>I want to start a command prompt but don't want any output from it. So I am starting it as -</p>
  
  <pre><code>cmd /q dir
  </code></pre>
  
  <p>which works fine but one cmd.exe doesn't exit. If I use this- </p>
  
  <pre><code>cmd /q /c  dir
  </code></pre>
  
  <p>I can see output of dir command which I don't expect to see </p>
