    Computer became really slow recently due to high CPU usage of Services and Controller app


    Service and Controller app constantly occupy ~40% of CPU causing my computer to slow down.I am using a windows 10 education version 1903By searching the internet I pressed Win + R and typed Eventvwr.msc, under error I found the "Service Control Manager" has a lot of errors all showing "The Realtek DHCP Service service terminated unexpectedly. It has done this 1 times." I wonder if this is why my computer is slow but I don't know what caused this and how do I fix thisThanks!

    It makes the machine really slow and useless

    Services and Controller app Random High CPU usage.

    Hi,



    Thank you for writing to Microsoft Community Forums.



    We understand your concern, as the Services and Controller app process is taking high CPU usage. We looked in to this and would suggest you to the PC in clean boot status and then check the CPU usage for Services and Controller app process. If the
    result is positive, then we need to check which app is guiding the Services and Controller app process to high CPU usage.



    Restart the computer by using a clean startup



    Disclaimer: Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program is causing the issue.
    Some of the Startup programs will not load after performing a clean boot on the computer. However, that functionality will return when you reset the computer to start normally after finishing the troubleshooting.



    To perform a clean boot on the computer refer to the article

    How to perform a clean boot in Windows    .



    If performing a clean boot fixes the issue then, please refer to the section
    How to determine what is causing the problem after you do a clean boot
    to check which program is causing the issue.



    Note: Please refer the section Reset the computer to start normally after clean boot troubleshooting
    to boot the computer in to normal mode after troubleshooting.



    In order to get clarity and to assist you further, please reply with the answers to the questions below.



    • Was there a major change or an update on your system, prior to which you weren't facing this issue?
    • What is the Windows 10 version and Build installed? (Type winver in Windows search/Run command)
    • What is the make and model of the PC?


    We await your response.

    Services and controller app very high cpu usage

    Hi,



    Thank you for writing to Microsoft Community Forums.



    We understand your concern as you are facing high CPU usage by the Services and controller app. We appreciate you effort in troubleshooting the issue and providing us a detail information



    In order to get clarity and to assist you accordingly, please reply with the answers to the questions below.



    • What is the Windows 10 version and Build installed? (Type
      winver in Windows search/Run command)
    • Are you aware of any recent changes on the PC, prior to this issue?


    While researching on the issue, we came across Dell website were we saw some recent hardware driver release, like BIOS, Chipset, Intel storage driver etc.



    We would suggest you to go to the

    Dell website     and click on detect PC, later you will get a list of drivers that needs to be installed. Please install them and restart the PC to check if you still facing the high disk usage.



    Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting
    properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.



    Please refer this article from Dell on How to
    Troubleshoot Slow Performance Issues



    We await your response.
