title: "Unable to launch the IIS Express Web server." in Visual Studio
body: <p>I attempted to run my web service through visual studio. I faced an issue like :</p>
  
  <pre><code>---------------------------
  Microsoft Visual Studio
  ---------------------------
  Unable to launch the IIS Express Web server.
  
  Failed to register URL "http://localhost:63591/" for site "xxxxxx" application
  "/". Error description: The process cannot access the file because it is being
  used by another process. (0x80070020)
  
  ---------------------------
  OK   
  ---------------------------
  </code></pre>
  
  <p>I saw the task manager and found that PID 4 is used by System and its Description is <code>NT Kernel &amp; System.</code>
  So I tried to stop the <code>http service</code>.
  All dependency services stopped. But I am facing an issue in stopping http service like</p>
  
  <pre><code>The service is starting or stopping.  Please try again later.
  </code></pre>
  
  <p>So, I tried to stop and start the service manually. But the End process is disabled. 
  It will be helpful if anyone could help with this issue</p>
