title: Periodically shut down a program
body: <p>I want to kill an executable of a game named KnightOnline and deny user to run it. I'm using:</p>
  
  <pre><code>Process.Start("taskkill.exe", "/f /im kol.exe");
  </code></pre>
  
  <p>but it's showing a command window. How can I hide the command window, or is there another professional but infamous method to deny an unwanted program?</p>
  
  <p><strong>EDIT:</strong>
  I edited hosts and blocked login page of the game as a solution.</p>
