With the Windows Drivers Model (WDM) for devices Microsoft implements an approach to kernel mode drivers that is unique to Windows operating systems. WDM implements a layered architecture for device drivers, and every device of a computer is served by a stack of drivers. However, every driver in that stack can chain isolate hardware-independent ...
But some sound card drivers can emulate more than one MME device (or support more than a single streaming client) so it could work with MME too. Starting from Windows 2000, MME supports playback device sharing (multi-client access) and can mix playback streams together. Starting from Windows XP, MME started to support recording device sharing.
One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup. If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.

Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
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.
DWM works in different ways depending on the operating system (Windows 7 or Windows Vista) and on the version of the graphics drivers it uses (WDDM 1.0 or 1.1). Under Windows 7 and with WDDM 1.1 drivers, DWM only writes the program's buffer to the video RAM, even if it is a graphics device interface (GDI) program.
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.
The Graphics Device Interface in the architecture of Windows NT For example GDK makes use of GDI. The Graphics Device Interface (GDI) is a legacy component of Microsoft Windows responsible for representing graphical objects and transmitting them to output devices such as monitors and printers. It was superseded by DirectDraw API and later ...
