I work for a training company, where some trainers play audio CDs during breaks, participant exercises, etc. In earlier versions of Windows and Windows Media Player, they could put a CD in the tray and it would play automatically behind the slide show. With Vista/WMP 11, inserting a CD always brings WMP to the foreground.

I have gone through all WMP settings, Program Features/AutoPlay settings and all WMP documentation and KB articles--to no avail.

Any ideas?

You just need to turn it off..(on by default)
press the Music Slideshow anb make sure the box is unchecked.
