What is Kernel-Mode Driver Framework?
Kernel-Mode Driver Framework is a set of libraries and tools that help developers create and maintain kernel-mode drivers for Windows. Kernel-mode drivers are programs that run in the same memory space as the operating system kernel, and they can directly access hardware devices and system resources. Examples of kernel-mode drivers include graphics drivers, audio drivers, network drivers, and storage drivers.
KMDF simplifies the development of kernel-mode drivers by providing a common interface and a set of features that handle common tasks such as device enumeration, power management, plug and play support, error handling, and security. KMDF also improves the reliability and performance of kernel-mode drivers by reducing the amount of code that runs in kernel mode, minimizing the chances of system crashes or hangs.

What is the history of KMDF?
KMDF is a part of the Windows Driver Frameworks (WDF), which is a set of tools and libraries that help developers create and maintain device drivers for Windows. WDF was first introduced in 2003 as a replacement for the legacy Windows Driver Model (WDM), which was complex and error-prone. WDF consists of two frameworks: KMDF for kernel-mode drivers and UMDF for user-mode drivers.
The first version of KMDF was released in 2006 as a download-only component that supported Windows XP and later versions of Windows. The first version of Windows that included KMDF was Windows Vista, which shipped with KMDF version 1.5. Since then, KMDF has been updated regularly with new features and bug fixes, and has been integrated into every new version of Windows. The latest version of KMDF is version 1.33, which is included in Windows 11 and Windows Server 2022.
KMDF has become a popular choice for developing kernel-mode drivers for Windows, as it simplifies the development process and improves the reliability and performance of drivers. According to Microsoft, over 90% of new kernel-mode drivers submitted to the Microsoft Hardware Compatibility Program use KMDF.
