title: How to close IIS Worker Process
body: <p>I was trying to install Visual Studio 2008 SP1 on my machine and I encountered this issue.

  <p>I looked it up, it looks like IIS Worker Process is some kind of   <a href="http://www.codeproject.com/Articles/125113/How-to-use-IIS-Manager-to-get-Worker-Processes-w3w" rel="noreferrer"> w3wp.exe</a>, so I looked into my Windows Task Manager and found out w3wp.exe is not running. I also took a look at my Worker Processes in IIS Manager and it wasn't started either. So, how do I close this application so I can continue my install or is there something else I can do? </p>
