Most let you block it all.
I see your question has prior discussions so I'm not going to duplicate answers but add what I see most miss. Install a firewall.

Background intelligent transfer service is eating my bandwidth. I have no idea what it is sending and receiving but it sucks 1.5meg of bandwidth all day long. If I disable it it turns back on after a while. This is probably some kind of virus, but if I can just keep the darn thing off, i'm ok with that.
