    This is very strange. Your left picture shows CPU usage of 50% but your right picture shows the system idle process at 91% - thus a CPU usage of 9%. Also the usage distribution between the two cores is very odd. All the load seems to be on the left core.
    I know it's strange. It only happens copying files over the LAN

    Tweek, do you by any chance have the ForeFront firewall installed?

    If so read this TechNet thread to the bottom of the page.
    High CPU Usage Windows Firewall

    Another TechNet thread with more possible solutions. Apparently this problem can be caused by a number of third party programs or drivers. Starting in safe mode may help to isolate the problem.

    So many have reported this problem it's difficult to pin point the cause.
    Windows 7 - svchost high cpu usage. - Super User

    AVG has also been known to cause this problem.
    Unnecessarily high CPU usage.
    My sig clearly tells which AV I use and it's not an issue with any other PC here or at home. I also mentioned earlier that I have tried in Safe Mode.

    I wonder if it has something to do with the way explorer is copying the files over the lan. I take it you don't get the same CPU usage when downloading files off the internet, etc.

    Try downloading TeraCopy or another third party file manager and try copying the files so that explorer isn't involved in the process. In fact, if you can, try copying the files through command prompt with explorer closed.

    Keep in mind I'm totally guessing, you're more than welcome to ignore me :)

    This actually might be worth a shot. Thanks, didn't think of that.
