6-min. laptop bootup time; which of these startup prog's can I disable

[teddyFBI]

So I made another post lamenting the fact that my laptop took 6-7 whole minutes to boot up from its 'off' state.

People said this wasn't normal and that it was possibly b/c I had too many programs set to automatically boot up. So I've finally got around to following one guy's advice to go into the msconfig...startup window and disable the things I don't need to start up, but I don't want to uncheck things that are potentially necessary processes for my computer. So hoping that some people here can take a quick look at the following list and tell me which ones I can safely disable (and which ones, I guess, will make the biggest/most noticeable difference in my startup time). You can see the 5 ones I unchecked, because it was pretty easy to figure out what they were and that they were unnecessary...but I don't know what all the other ones are so I'm wary to uncheck them.
