Maxflyer,
Check Start >> Programs >> Startup
Pretty much anything in there can be deleted. If it is in that folder, it means that it loads when the computer starts, but it is not critical for using that software. If it were critical, they would have added it to the registry instead of the startup folder to make it load on bootup.
Take Care,
Richard
P.S. A list of programs you have running in the background would give us a chance to look over and tell you which can safely be disabled.
