After digging all day on this problem, I found some more. Windows update not working but got that fixed. Microsoft security essentials not updating, but uninstalled that all together and got a symantec endpoint protection for free from my company, and also did a system restore to a few days back. I don't know for sure, but the games I downloaded between then and now must have been the root of the High CPU usage, because its no longer there. I'm running at a cool 5% again. Must have been an opening in the network allowing these games to update. Starcraft II, Tropico 4, Dragon Age II.
