disable the force restart at the end of WBADMIN systemstaterecovery Win2008R2?

I invoke WBADMIN to perform a system state recovery on Win2008 R2. At
the end of recovery, WBADMIN prompts to enter Y to restart the
machine, and WBADMIN does not terminate unless user entered Y. Even
if I terminate WBADMIN, the machine is already in a pre-shutdown stage
where I cannot start any new process that loads DLL (error was
0xC0000142).

I could not find any option to disable this behavior for system state
recovery (http://technet.microsoft.com/en-us/library/cc742035(WS.
10).aspx).

WBADMIN on Win2008 does NOT force a restart at the end of system state
recovery.

I need to disable this force restart because
I am using a VBS script to invoke WBADMIN for system recovery, and I
need to perform additional operations (copy files, and notify the
caller that VBS is done successfully) after system state recovery
completes.

Any recommendation or pointers are appreciated.

Thanks.
