Windows Kernel - Fix Kernel Security Check Failure Error [MiniTool Wiki]
About Windows Kernel
Windows is one of the most flexible operating systems. The operating system currently supports x86, x64, ARM and ARM64 architectures.
Before intruding Windows kernel, let’s learn about kernel at first.
What is kernel? Kernel is a computer program that is the core of a computer’s operating system, with complete control over everything in the system.
When a computer is powered on, its kernel goes through some initialization function, such as checking memory. It takes responsibility for assigning and unassigning memory space which allows software to run.
There are two types of kernels:
- Micro kernel: only contains basic functionality.
- Monolithic kernel: contains many device drives.
What is Windows kernel? Windows kernel is the core of Windows operating system, and the core scales dynamically depending on the architecture and the processor that it is run on to exploit the full power of the hardware.
Windows kernel refers to Windows NT kernel and Window 9x kernel. Let’s see some information about the former one.
Windows NT Kernel
Windows NT kernel is a hybrid kernel containing a simple kernel, hardware abstraction layer, drivers, and a range of services.
It is a layered design that includes two main components, namely user mode and kernel mode.
User mode: The layer is made up of the “Environment subsystems”, which is between user mode applications and operating system kernel functions, and “Integral subsystem”. Programs and subsystems in this mode are limited in terms of to what system resources they have access.
Kernel Mode: The mode has full access to the hardware and system resources of the computer and runs code in a protected memory area. It controls access to scheduling, thread prioritization, memory management and the interaction with hardware.
Kernel Mode is preemptive and reentrant, and it aims to work with uniprocessor and symmetrical multiprocessor (SMP)-based computers.
It is responsible for the thread dispatching, multiprocessor synchronization, hardware exception handing, and the implementation of low-level machine dependent functions.
