Systems Management

I'm not sure if this is the right place for this question or if it is even possible as we have had our Kbox for just over a week and have not started formal training just yet but I am eager to get going. I have already installed the agents and the inventory is building.

My question is, how can I (if at all) disable startup programs globally? The latest Windows up seems to have installed Windows Messenger Live on our employees desktops and we need to disable that on all of them.

Thanks for any help.
