Hi,
Please read the below discussion;

That sheds some light however before we blocked llnw.net it moved 700 megs on one workstation even though we find no traces of p2p or malware. The only traffic we seen moving was related to microsoft. We then found workstations that had automatic updates installed were showing failed and the firewalls starting logging that updates.microsoft.com were blocked along with a stats.microsoft.com were being blocked.
