  1. Windows Defender High CPU Utilization


    I have an HP Notebook 15-f387wm, and it currently has an integrated quad-core processor by AMD. It recently has developed a bug with Windows Defender. I noticed that it was using almost 50% of the CPU, causing the laptop to go over 60°C, even when the laptop is idling. I checked if Windows Defender was running any scans, and it wasn't doing any scans at all. I've tried a factory reset, and I have tried restarting the laptop. I need to fix this issue permanently so that I can actually play games, which was what my laptop was made for.

    :)

    TokenBroker services causes high CPU utilization?

    We have Windows 10 Pro version 1703, 64bit.

    We see CPU stay at 50-60%, and spike up to 99-100% for extended times. We have been able to isolate the high CPU to the Token Broker service by using the Windows Performance Recorder and Analyzer.

    We understand this service has something to do with the Windows Store and Authentication and was added in with the Anniversary update. With it turned off, we return to normal CPU utilization, but we are unsure if this service is a requirement.

    Microsoft is a bit ambiguous on this service, even the description for the service reads "<Failed to Read Description, Error Code:1500 >"

    • Because there isn't a lot of documentation on this we are unsure if we even need this service. Can we simply disable this service permanently?
    • Is anyone aware of the Token Broker service causing high CPU like this?

    CPU won't go above 23% utilization

    I have a custom built PC. specs are below. After some recent problems and a full windows reinstall it seems that my CPU won't go above 23% utilization. I have set the power plan to high performance and am using Prime95 to attempt to stress the CPU. When
    I look in the BIOS everything looks correct. The CPU temp is reasonable, it detects the CPU as 3.4ghz. Windows also detects that the model of the CPU is correct and lists it as 3.4ghz in system properties. When viewing the CPU on the performance tab of
    task manager is lists the speed as 0.78 GHz and that number never changes. It's like it's stuck on that number. Any help on how to troubleshoot this problem would be appreciated!

    CPU: Core I7-6700 @ 3.4ghz

    Motherboard: Gigabyte GA-H170M-DS3H

    Bios Version: F22e (latest)

    Graphics: Onboard Intel 530

    RAM: 16gb DDR4 2133

    PSU: 550w

    Power plan: High performance

    Edit:

    Additional Troubleshooting steps:

    Reset BIOS to default values - Issue still occurs.
