Altiris 7.1 Client Management-Possible to query database for client regkeys?

We are running altiris 7.1 with Win7 clients.  I need to query for a specific regkey on all my clients.  I can script a reg query to hit all machines, but it will only get to the ones that happen to be turned on and will take a long time.  Is there anything in the Altiris database that might happen to have that information?  Going after regkeys in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SharedAccess and HKEY_LOCAL_MACHINE\Comm\Mbridge

I am guesing this information is not collected, but if there is a way or table I can look through, please let me know.

Thanks,
