The AutoPlay feature in a Windows operating system automatically opens removable media files using default applications. CyberLink PowerDVD is one of those default and preinstalled applications that comes free with the operating system. However, if you want to use another software to play back your DVD movies, then you can either change the default program, set Windows to ask you what program to use before playing or disable the AutoPlay on DVD movies altogether.
