After implementing the Windows Update, the CPU usage and disk usage of "ntoskrnl.exe" are quite high.
Do you have any information about the Ntoskrnl .exe, such as the cause and how to deal with it?

    Hello

    Ntoskrnl.exe is a system process, and it’s also known as the “Windows NT Operating System Kernel Executable”. It’s related to a kernel, which is a piece of software that connects hardware and software. Many different Windows services depend on this kernel to function efficiently.

    You can try the following methods to fix the problem of high CPU usage:

    1. Update the driver
    2. Use DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow commands to repair corrupted system files
    3. Use the CHKDSK command to check for disk errors

    If these actions do not fix the issue, it is recommended to use the perfmon tool to collect specific information on high CPU usage:

    Hello there,

    Ntoskrnl.exe, short for Windows NT operating system kernel, is a fundamental part of the system.

    I would suggest you to perform a clean boot and see if that helps. You can follow the steps from here https://support.microsoft.com/en-us/topic/how-to-perform-a-clean-boot-in-windows-da2f9573-6eec-00ad-2f8a-a97a1807f3dd

    Try performing a full system scan for your computer to see if there are unwanted programs and script that slowdown your computer's performance.

    The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.
