As invoker (default)
The AutoPlay application runs with the same access token as the parent process. For example, if the user is logged in as a standard user, those are the privileges they will inherit during the running of the application. This option is generally used for AutoPlay applications that are presentations or menus, where you are certain you do not need access to protected areas of the operating system (file system/registry). This includes access directly by the AutoPlay application, and the launching of external programs that require these permissions (unless they are designed to handle their own permission detection and notification). See Running on Windows Vista or Later for additional details.
