When you turn on your computer certain applications, drivers, and services are automatically started at the beginning of each Windows session. The information that tells Windows to automatically start these items can be located in a number of places, ranging from a program group on your Start Menu, to certain initialization files that are executed when Windows starts, to one of many places in the system registry. The StartUp manager tool lets you centrally manage all of these items using one single interface. Using the StartUp manager you can easily add, remove, edit, disable, and enable any and all of these "startup items" in order to keep your system's boot-up process as fast and efficient as possible.

How do I find out if a program that starts automatically is necessary?

When you select a startup entry in the list, StartUp Manager displays detailed information on the program in the Details box at the bottom of the window. You can easily determine whether or not you wish to have the program started on the basis of the Product name and Company. If you have never heard of the company or the product, then the entry is probably not needed.You can also find it's more information from internet ,to do this,right click your mouse and select 'Search Google' on the popup menu.
