Well, i mean AUTORUN, not AUTOPLAY... (I know it was just the same, but the autorun reads the autorun.inf on CDs and another removable media, [and even disk drive] and run program in the media whose path was listed on the .inf files, meanwhile autoplay just detect the type of the files inside the media and run the appropriate program for it...) And i forgot to tell one more thing, even the windows' media change detection were disabled! (the title of the CD was not displayed, instead the name of the drive BEFORE the CD inserted, ex: when i put my Balnk CD on the drive, usually the title of the drive changed into "Blank CD", but whatever i do, it's always displayed the old title; it's only works when i restart it)
