I have a ton of programs that start automatically when I boot up my system. I'm running windows ME. What do all these mean and what can I safely take off the start up list?

creative launcher
explorer
ctfmon
winmgmt
wdm
money express
qbagent2001
mrtmngr
mediadet
mm_tray
ctavtray
ctnotify
point32
systray
updtray
ahqtb

Do I really need all of these????

Thanks for any assistance!
