    CPU running at 100% after the last Windows update!


    The weird thing is that when I open the task manager window, the CPU usage goes lower. And when I close it, It rise again to 100%!!

    Should I go back to the previous version? Or what exactly should I do?


    Thanks in advance.

    :)

    100% CPU Usage after Windows 10 upgrade

    Hello Aaron,

    Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

    Most of the time, computers only use a small fraction of their CPU power. In fact, many computers use less than 5% of their CPU most of the time. When you open an application, play a video game, or encode media file, the CPU usage will rise or spike temporarily.
    Once the CPU intensive process completes, the CPU usage should once again drop down to lower level. Most applications will not use up more than 50% of your CPU for an extended period of time. However, some programs and system processes can use up a large amount
    of CPU without you even knowing it. This may happen if a program gets stuck in an infinite loop or encounters an unexpected error.

    I suggest you to perform Safe mode and Clean boot procedures on the PC by following the steps below.

    Step 1: I suggest you to boot your PC in Safe mode by following the steps from the link below and check if the issue is resolved.

    Safe mode is a diagnostic mode that starts your computer with limited drivers necessary to run Windows. The words
    Safe Mode appear at the corners of your monitor to identify which Windows mode you are using.

    Expand the options to boot into Safe Mode:

    http://windows.microsoft.com/en-in/windows-10/start-your-pc-in-safe-mode



    Reboot the PC to exit from Safe mode.

    To know more about Safe mode, following is an article on
    Windows Startup Settings (including safe mode)
    (Applies to Windows 10 also):

    http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-safe-mode

    Step 2: If the issue persists, perform Clean boot on your PC by following the steps from the link below and check if the issue is resolved.

    Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue.

    I suggest you to perform clean boot by following the steps from the link below and check if the issue is resolved.

    You can open the system configuration window in Windows 10:

    a. Using run command.

      • Press Windows Key + R keys on the Keyboard.
      • Type msconfig.msc and press Enter.

    b. Using Cortana.

      • Press Windows icon key on the keyboard and type msconfig.
      • Select the top most search result.
    Follow the steps from 3 under How to perform a clean boot
    for Windows 8.1 and Windows 8 from the link below (The steps for clean boot suggested in the link below for
    Windows 8/8.1 is applicable for Windows 10 as well):

    https://support.microsoft.com/en-us/kb/929135

    Disclaimer: Start the computer in normal mode refer the section,
    How to reset the computer to start normally after clean boot troubleshooting
    from the link above.

    Write to us with the status of the issue on the same post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

    Thank you.
