title: Close a running application from DOS command line
body: <p>The start command can launch an application like notepad in a batch file like this:</p>
  
  <pre><code>start notepad
  start "my love.mp3"
  </code></pre>
  
  <p>But how do I close the running application from the command line? I found <code>taskkill</code> in my searches but I don't think that is the right command because it's not working&mdash;it says no such file.</p>
  
  <p>How do I close an application launched with <code>start</code>?</p>
