Something similar, but not called MSCONFIG. Its "Services" found in Control Panel|Admin Tools. However, probably what you are looking for are the running background task that you can start/shut-down. Well, if thats the case, doa a Ctrl-Alt-Del, then click on "Task Manager" button and then "Processes" tab. From here you can right click on a task to disable it, but logon as Admin first. BE CAREFUL.
