BleepingComputer.com: Help with removal of Startup Programs

I just went round to my girlfriends house and they want me to help them speed up their computer, i got rid of all the junk they dont need like games they have installed and done a full defrag and disk cleanup too. they told me the thing that takes the longest is the computer loading up, now i know what some of programs are but i just wanted help on what ones i can safety remove without causing any harm to the computer?

There is a link to the screenshot that shows their current startup programs.

If the Link doesnt work the programs are

VTTimer.exe
iTunesHelper
apdproxy
dumprep 0 -k
mcagent
SiteAdv
McENUI
justched
vsnpstd3
QTTask
msmsgs
phototoolkitmem
ctfmon
E_SD7
camtool
Microsoft Office (Keeping obv.)

Did you research these in the startup database yet?
