How To Enable Autorun for Other Removable Media

Autorun can be enabled or disabled for all Removable media types, such as a floppy or Zip disk. Windows systems are configured to enable CD Notification, other removable media are by default disabled. 

The System Properties User interface only exposes the CD Enable or Disable selection. 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. Modifiying the Registry is not for the inexperienced user. Anyone will tell you, be VERY careful.
   2. The modifications made in this case use Hex not Decimal numbers. If you are unfamiliar with the Registry or the characteristics of base numbering and Hex, studying these topics prior to making these modifications is advisable. 

To Modify these 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.
