[HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \BITS]
DelayedAutoStart = 1
Start = 2

Note the "Manual" startup mode was extended with "Manual (Trigger Start)" with Windows 7/2008 R2. It specifies that the service startup can be delayed until a certain event occurs (or be stopped). See what service trigger eventsthat are configured for a service with this command:
