Microsoft has attempted to reduce system instability due to poorly written device drivers by creating a new framework for driver development, called Windows Driver Frameworks (WDF). This includes User-Mode Driver Framework (UMDF) that encourages development of certain types of drivers—primarily those that implement a message-based protocol ...
The first version of the UMDF was shipped as part of Windows Media Player version 10 on 2004-10-12. Code-named "Crescent", it was designed to support the Media Transfer Protocol driver, and no public interfaces or documentation were provided for it. Later, Microsoft decided to turn UMDF into a device driver development platform. [3]
The Windows Dev Center - Hardware pages explain upper and lower filter drivers in detail. [2] For example, the generic USB camera (UVC) driver usbvideo.sys is a function driver, while the bus driver handles USB data from the host controller devices. A lower level filter modifies the behavior of the camera hardware (e.g. watching for interrupt ...
Windows Driver Frameworks (WDF, formerly Windows Driver Foundation), is a set of Microsoft tools and libraries that aid in the creation of device drivers for Windows 2000 and later versions of Windows. It complements Windows Driver Model, abstracting away much of the boilerplate complexity in writing Windows drivers. WDF consists of Kernel-Mode ...
The turn of the millennium saw the widespread introduction of solid-state removable media, with the SD card being introduced in 1999, followed by the USB flash drive in 2000.

WDM is the driver model used since the advent of Windows 98, whereas KMDF is the driver framework Microsoft advocates and uses for Windows 2000 and beyond. In general, since more features like power management and plug and play are handled by the KMDF framework, a KMDF driver is less complicated and has less code than an equivalent WDM driver.
