Autoplay is a function in Windows that will allow music files, pictures, video files, mixed content CDs, music CDs, DVD movies or HD DVD movies to automatically play when the disk, flash drive or other removable media is inserted into your computer. This function can be controlled by media type and drive. If you want Windows to open Windows Explorer or to take no action at all, you can also select those functions within the Autoplay settings.
Double-click "My Computer," right-click on the drive you would like to Autoplay and click on "Properties."
