How To Enable or Disable “AutoRun” for removable media

AutoRun can be enabled or disabled for all Removable media types, such as a Floppy or Zip disk, and USB Flash Drives. This is useful to know because removable media can easily be infected with viruses and spyware that is configured to install when removable media is inserted into the PC. Windows systems are configured to enable CD Notification, other removable media are by default disabled, but if for some reason they aren’t, then it is a good idea to disable them.

The System Properties User Interface only exposes the CD Enable or Disable option. The setting reflected in this dialog makes an entry in the System Registry. It is in this same location that other media types are configured.

Notes:

1. Modifying the Registry is not for the inexperienced user. Anyone will tell you to, be VERY careful.

2. The modifications shown below use Hexadecimal not Decimal numbers. If you are unfamiliar with the Registry or Hexadecimal, looking into these topics prior to making these modifications is advisable.

To Modify the following Registry Settings, Use “Regedit” and navigate to the following Key:

HKEY_CURRENT_USER

Software

Microsoft

Windows

CurrentVersion

Policies

Explorer

“NoDriveTypeAutoRun”

The default value for the setting is 95 0 0 0. Change the first byte to 91. Restart the computer to make the new setting take effect. You may have to right-click on the floppy and choose AutoPlay from the menu to see the AutoPlay behavior.
