title: Cycle through open Windows applications
body: <p>I need some help on which way to go with something that seemed at first like a very simple requirement.</p>
  
  <p>I have to find a method of cycling through open applications on a Windows PC, with the objective of displaying the windows for say 30 seconds at a time on a large screen mounted on a wall. Typically there will be an MS Access report and a couple of web pages.</p>
  
  <p>My initial thinking was that I could open these apps manually on the PC, then run a VBScript to cycle through them. However there were two problems with this. </p>
  
  <ol>
  <li>Simulating the Alt+Tab keypress just toggles the two most
  recently used apps instead of cycling through them all, and</li>
  <li>There is no possibility I can see for the user to be able to
  escape out of the script using a keypress.</li>
  </ol>
  
  <p>Can anyone suggest how I can achieve this using resources already available on a Windows (XP upwards) machine?</p>
