Service Dependencies allow services to be started (and stopped) in order. They specify which services or load order groups must be running on the machine before this service can run. For example, if the service ServiceA depends on the pre-requisite service ServiceB, then Windows will always start ServiceB before ServiceA during a machine boot-up. Similarly, if both ServiceA and ServiceB are stopped, then manually starting ServiceA will firstly cause ServiceB to be automatically started. Similarly, stopping ServiceB manually will force ServiceA to stop. Interestingly, services dependencies are not used during machine shutdown.



Click on the drop down lists and choose a service or a service Load Order Group to make this service depend on. The service short name or Load Order Group name will be automatically listed in the corresponding list box. If you are running on Windows Vista, 2008 or later make sure your services (especially if they are interactive) depend on the Interactive Services Detection service (UI0Detect).
