The AutoRun CD information is great if you want the PowerPoint to start
as soon as the CD is inserted. If you just want the PowerPoint to start
when the file is double-clicked, then you just need to save your file as
a PowerPoint Show (.pps). Either rename the file to have a .pps
extension (instead of .ppt), or choose Save As from the file menu (while
you are in PowerPoint and for the type of file, choose PowerPoint Show
(*.pps).
