How do I set a service startup type to be 'Automatic (delayed)' using GPO?

Question

A Windows service has 4 different startup types that can be configured: Automatic, Automatic (delayed), Manual and Disabled.

I have a service running on a combination of Windows 7 and Server 2008 R2 Desktops that I need to set as 'Automatic (delayed)' using a GPO setting, but from what I can see in the GPO editor, the delayed option is missing:

Have I missed something obvious, or is this a rather basic omission from Microsoft?

Solution

You need to user Services preference extension which allows to configure existing services on client machines via GPO.

More options for configuring services via GPO. Should work with W7, haven't tried on earlier client versions.
