Deploying Windows Updates during a Task Sequence

I'm trying to deploy all available Windows 7 updates as the TS finishes, but it looks like they're not getting deployed as the TS finishes. While the computer sits on our working bench, eventually the updates get deployed.

I did some research and found this article, but this suggestion seems not to work for us.

Is there anything else I can do to make sure all my newly deployed machines get all updates as the TS finishes?

Thanks!
