This policy setting disallows AutoPlay for MTP devices like cameras or phones. The recommended state for this setting is: Enabled. Rationale: An attacker could use this feature to launch a program to damage a client computer or data on the computer. Impact: AutoPlay will not be allowed for MTP devices like cameras or phones.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled: Computer Configuration\Policies\Administrative Templates\Windows Components\AutoPlay Policies\Disallow Autoplay for non-volume devices Note: This Group Policy path may not exist by default. It is provided by the Group Policy template AutoPlay.admx/adml that is included with the Microsoft Windows 8.0 & Server 2012 (non-R2) Administrative Templates (or newer). Default Value: Disabled. (AutoPlay is enabled for non-volume devices.)
