Once enabled, it monitors and stresses drivers to detect illegal function calls or actions that may be causing system corruption. It acts within the kernel mode and can target specific device drivers for continual checking or make driver verifier functionality multithreaded , so that several device drivers can be stressed at the same time.

However, due to performance issues of hardware of that age, it was decided to move the graphics subsystem into kernel mode. As such, system call in the range of 0x1000-0x1FFF are satisfied by win32k.sys (instead of ntoskrnl.exe as done for 0-0x0FFF), and are declared in user32.dll and gdi32.dll.
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.
The Blue Screen of Death in Windows 9x, as it appears on Windows 95 and Windows 98. The Windows 9x line of operating systems used the Blue Screen of Death as the main way for virtual device drivers to report errors to the user.
Kernel Patch Protection is the technology that enforces these restrictions. It works by periodically checking to make sure that protected system structures in the kernel have not been modified. If a modification is detected, then Windows will initiate a bug check and shut down the system, [6] [8] with a blue screen and/or reboot. The ...
Useful for troubleshooting performance problems and defective CPUs. [7] /ONECPU – Equivalent to using /NUMPROC=1. Causes Windows to use only one CPU on a multiprocessor system. [8] /PAE – Enables Physical Address Extension support. In Safe Mode, the computer starts by using normal kernels, even if the /PAE switch is specified. [7]
As an oops could cause some subsystems or resources to become unavailable, they can later lead to a full kernel panic. On Linux, a kernel panic causes keyboard LEDs to blink as a visual indication of a critical condition.
A kernel panic is the Unix equivalent of Microsoft's Blue Screen of Death. It is a routine called when the kernel detects irrecoverable errors in runtime correctness; in other words, when continuing the operation may risk escalating system instability, and a system reboot is easier than attempted recovery.
