ntoskrnl.exe

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:

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.
