I use the enterprise version, so yeah, it has everything.
Since I have to use this to test my software, I don't tweak the OS in any way, I let everything run, connected to the net, etc. Stock, right outta the box (I figure the majority of my customers would probably not tweak).
Vista comes up on my machines with about 42 processes running. My XP machine that I actually develop on, usually has about 60-65 going.
As I'm typing this, my latest software is running two videos on a second monitor on the same machine, over 1GB memory commit, and 60 processes going, including two compilers, email, editors, Paint Shop Pro, 6 tabs in FireFox, etc. This is not a fast machine either. That's my little "secret" to software development -- do it with all the junk running, and it will run better on everything else
FYI:
The only software I won't run, is iTunes and MusicMatch, as they have a terrible habit of hooking the audio drivers, and not letting go, which screws up any other audio software on the machine. Also, Alienware ships some weird GI skins with their computers now too, that causes some problems with other software (that came from a couple customers using XP).
