    It seems my problem has vanished immediately after cancelling my bitdefender subscription and uninstalling

    No issues at all since

    Thanks for all the help and tips it has been very educational

    I can confirm that Bitdefender Total Security 2016 is the culprit causing this problem on my system. After disabling the Firewall the CPU load went down immediately. Thanks at gooner1959 for mentioning that disabling Bitdefender solved your problem. I spent the last week trying to get rid of it myself including a full system reinstall
    I'm actually having issues with usbport.sys myself, but I don't have Bitdefender installed. I tried disabling Windows Defender and Windows Firewall, and neither change had any effect on ISR count or DPC count in LatencyMon. Can you guys please confirm that you're not getting any high numbers for usbport.sys in LatencyMon? Thanks.

    Hi, similar here - usbport.sys + no Bitdefender

    Yes, I read through a number of different threads prior to posting here. I'm still interested in hearing about what usbport.sys is doing in LatencyMon for the two posters quoted above. As I said, disabling Windows Defender and Windows Firewall, neither change had an effect for me. Gooner and Cruelly seem to think that the issue is resolved. I'd just like to know what LatencyMon is reporting. Is ISR count now zero for usbport.sys in LatencyMon, for example, now that Bitdefender is disabled?

    Fair question..
    Some things that have helped others:
    Have you tried updating all Intel drivers for your MBO?
    BIOS update?
    Disabling your LAN card or using an older driver?
    Use high performance power plan (workaround, not fix)
    Use bluetooth audio (workaround, not fix)

    But what would be better would be a means of analysis to show what's happening - other than Xperf and LatencyMon it seems.

    I don't mean to hijack the OP's thread, but since I'm being asked, and because what I say might help, I'll quickly go over some of the things that I've tried to resolve the issue.

    - I'm on a fresh install of Windows 10 Professional on a brand new HDD (Western Digital 1 TB Black).
    - I'm still on the X58 chipset, but I've flashed my motherboard (Gigabyte EX58-UD5) to the latest version (F13).
    - All of my drivers are currently up to date.
    - I've tried disabling anything that I don't use. However, I don't have a PS/2 keyboard, so I haven't tried disabling my USB 2.0 controllers completely. I've tried disabling all but one of my USB controllers, using devices in different ports, etc.
    - I'm on high performance with processor power management min/max states at 100%, and USB selective suspend disabled.
    - I've disabled HPET in BIOS. For some reason it defaulted to enabled in 32-bit mode when I installed Windows. When disabled, latency was dramatically reduced in LatencyMon for a number of different drivers (except for usbport.sys). Tried to enable 64-bit mode, no change regarding usbport.sys.
    - I disabled onboard audio, as I'm using an Asus Essence STX II for sound. I have the low latency version of the Unified Drivers installed.

    As far as I can tell from examining LatencyMon, usbport.sys is currently the only red flag for me. ISR count, DPC count, and Total Execution Time skyrocket and get MUCH worse (higher) when I move my mouse around on the desktop.

    Hi, have you disabled sound enhancements?
    What is your System interrupts process CPU usage?
    Are you using a wireless or wired mouse?
    Any IRQ conflicts?

    - All sound effects disabled. Using 16 bit, 44100 Hz.
    - System interrupts remains under 1% most of the time
    - I'm using the Logitech G502 (wired mouse)
    - No IRQ conflicts as far as I know. I've checked.

    Like I said, usbport.sys is the only driver that's giving me trouble. My system seems to be running fine otherwise.

    This is LatencyMon running for 1 minute. And I realize that LatencyMon should be run for longer than one minute. This is only to illustrate that usbport.sys is very clearly a problem. I have most applications closed, and I'm just moving my mouse around on the desktop:

    Hi, a couple of ideas here:
    Solving DPC Latency Issues | SweetCare

    Have you tried a high performance power plan?
    (not ideal...)
    I've just noticed the PCI Express settings differ between balanced and high performance

    Yes, I indicated above that I'm on high performance with processor power management min/max states at 100%, and USB selective suspend disabled.

    Ok, how have you checked your drivers are up to date? If you've just done a normal Windows check, then you're using the MS database or whatever they use.

    Suggest you try other means as an experiment, with due precautions, noting that Windows will quite quickly replace drivers different to said database, looking for MBO drivers in particular.

    E.g. a scan with Drivermax
    (Normally we steer clear of these things, but carefully used they can be helpful. It has found me two drivers - for a USB device and one for my old laptop Windows didn't find for Win 10 and no chance on manufacturer's site).
