Ntoskrnl.exe is a chief operating system that handles memory operations in Windows 10. Another name for this file is (Windows NT operating system kernel or kernel image). The kernel image is responsible for providing the executive and kernel layers of Windows NT with sufficient kernel space.

If a task is loaded to your RAM along with the task executor program, the Central Processing Unit (CPU) will execute the task, after which it will record results in the memory at first and later by the loaded program. This action also has access to several devices in your PC, such as the CPU, GPU, ROM, HDD, and SSD. After the program is closed, the task is removed from the memory as well as the data is processed to free up space for newer tasks.
Although the kernel system file manages memory space, it tends to consume quite a lot of space, most of which are caused by hardware and malware viruses, leading to memory leaks.
