If you have an audio CD or USB drive, you can disable autoplay so that the discs don’t start playing automatically. To do this, open the device’s Properties dialog and click on the AutoPlay tab. Under AutoPlay settings, make sure that the box next to “Autoplay for CDs and USB drives” is unchecked.
To get to the configuration screen for this setting, go to Start Menu \ Run and type in:
You will see the Group Policy window. You should select Administrative Templates \ System in the tree view:
You will see an item in the right side pane called “Turn off Autoplay”
Double click the item, and set the radio button to Enabled, and change the “Turn off Autoplay on” to All Drives.
Now you should be safe from the autoplay monster.
