Generally, once into the start up part as VoG™'s links suggest DO NOT delete anything or stop something starting from the start up unless you understand completely what it does if that is what you mean.
On the whole unless you know you have a lot of programs on start up it should not be a problem, but some sneak in so it could slow things up. Are there start ups you are unsure about? Do you want to post here for a view?
My God,Never seen so many programs on Start up before,Must have taken ages for your computer to start, I have 6 on mine,Sorry I cant help you with this problem,But I dont think it will take long for someone to fix it,Will leave it for the experts.
