It's probably the updating of the Metro apps which occur even if you aren't using them. Yes it sucks, but that is Windows 8 for you. It will eventually stop when the current round of updates has finished, that is, until the apps are updated again.
Window apps are very download inefficient and space inefficient on the computer, another reason why I hope their stupidity regarding Windows 8 leads to a fail, because the worst thing for the consumers is to have it be successful. I'm not saying the whole thing is all bad, it's just the way it is was planned out, and the typical PC user is the big loser.
