Hi Robert. Welcome to BleepingComputer.
This is the intro section so you will not get many replies to a question here, in future try and find a more appropriate forum and I am sure you will be helped..
However, at the top of every page there is tab called Start Up List. You can check there whether or not a program is necessary.
A very easy way to handle your startups, is to use WinPatrol. This program will also give you lots of info about your computer and is very handy to have.http://www.winpatrol.com/download.html
Browse around and enjoy.
