AutoPlay, a feature introduced in Windows XP, examines newly discovered removable media and devices and, based on content such as pictures, music or video files, launches an appropriate application to play or display the content. It is closely related to the AutoRun operating system feature. AutoPlay was created in order to simplify the use of peripheral devices - MP3 players, memory cards, USB storage devices and others - by automatically starting the software needed to access and view the content on these devices. Unfortunately, for some people it is simply an annoyance that causes the AutoPlay window to open every time they insert media into their PC.
