    Can anyone tell me why SYSTEM always shows high network load almost all the time even when idle? Motherboard is a ASUS Sabertooth 990fx R2.0 AMD AM3+ 8750 with 32GB RAM and Samsung 850 SSD using built in ethernet/lan port not wifi. Cant say for sure if this was an issue with TH2.

    Turns out it was a SMB SHARE SYNC (SmartSync Pro) I had running on another device on my LAN. It was copying files from the other device to my ASUS PC. Totally forgot about that. Not sure why it didnt show an open session in fsmgmt.msc but SmartSync running a sync on another PC was the cause. Thanks 100 for getting me thinking in that direction.

    Something reading from or writing to a network share on your machine would be my guess.
    Check fsmgmt.msc for open sessions.

    I checked. No open session. Maybe I will just have to start killing processes until it stops or at least chills out. Its all over the map but about 95%+ most of the time.

    But, it is your system that is the culprit there. It's indicated as using most of your nexwork. Disconnect the network and check for changes.

    I think that M$ can and will use your bandwidth in order to download updates for someone else near you, their version of using P2P tech

    The "System" process is what runs kernel-mode threads, so whatever is doing the I/O is going to be related to a kernel-mode driver. It may not necessarily be caused by a user-mode process.

    Are you running any third-party AV or firewall?
