Ntoskrnl.exe is a crucial file in the start-up process for the Windows operating system. Despite its importance, it should never appear in the processes or the tasks of a running operating system.

Remove the ntoskrnl.exe if it is appearing as a process and is stored in a folder other than the Windows system directory.

Close the Explorer and return to the desktop. Right-click the recycling bin and choose "Empty" to remove the file from your computer.
