Autoplay starts to read from a drive as soon as you insert media in the drive, which causes the setup file for programs or audio media to start immediately. An attacker could use this feature to launch a program to damage the computer or data on the computer. You can enable the Turn off Autoplay setting to disable the Autoplay feature. Autoplay is disabled by default on some removable drive types, such as floppy disk and network drives, but not on CD-ROM drives. Note You cannot use this policy setting to enable Autoplay on computer drives in which it is disabled by default, such as floppy disk and network drives. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\AutoPlay Policies!Turn off Autoplay (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer!NoDriveTypeAutoRun
