How can I fix high CPU or disk usage by Ntoskrnl exe. in Windows 10?
Ntoskrnl.exe is a Windows system process that controls essential functions such as memory management and hardware abstraction. If it is causing high CPU usage or a blue screen of death (BSOD), solutions may include checking your PC's memory, disks, updates, and system files.
When you boot up a Windows PC or laptop, various system processes are activated. They generate the user interface that you use to log in and start working, but are also responsible for various under-the-hood actions that you are not even aware of, such as managing memory and communicating with other network devices.
