Its CPU time "usage" is a measure of how much CPU time is not being used by other threads. In Windows 2000 and later the threads in the System Idle Process are also used to implement CPU power saving. The exact power saving scheme depends on the operating system version and on the hardware and firmware capabilities of the system in question.
ntoskrnl.exe (short for Windows NT operating system kernel executable), also known as the kernel image, contains the kernel and executive layers of the Microsoft Windows NT kernel, and is responsible for hardware abstraction, process handling, and memory management.
Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process. After the user has successfully logged into the machine, winlogon applies User and Computer Group Policy setting and runs startup programs declared in the Windows Registry and in "Startup" folders.
The Session Manager Subsystem is the first user-mode process started by the kernel. Once started it creates additional paging files with configuration data from HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management, [1] the environment variables located at the registry entry HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment, and DOS device mappings (e.g. CON ...
On x86-64 and Itanium platforms there is just one possible hal.dll for each CPU architecture. On Windows 8 and later, the x86 version also only has one HAL. HAL is merged (or statically linked) into ntoskrnl.exe [2] starting with version 2004 of Windows 10, and the dll only serves as a stub for backwards compatibility.
In a multiprocessing environment with more than one logical processor (i.e. multiple cores or hyperthreading), more than one task can be running at the same time.However, a process or a thread can be set to run on only a subset of the available logical processors.
Resource Monitor, a utility in Windows Vista and later, displays information about the use of hardware (CPU, memory, disk, and network) and software (file handles and modules) resources in real time. [1] Users can launch Resource Monitor by executing resmon.exe (perfmon.exe in Windows Vista).
Windows NT 3.1 is the first major release of the Windows NT operating system developed by Microsoft, released on July 27, 1993.It marked the company's entry into the corporate computing environment, designed to support large networks and to be portable, compiled for Intel x86, DEC Alpha and MIPS based workstations and servers.
