In computing, the Windows Driver Model (WDM) – also known at one point as the Win32 Driver Model – is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model.
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.
The WMI extensions to WDM provide kernel-level instrumentation such as publishing information, configuring device settings, supplying event notification from device drivers, and allowing administrators to set data security through a WMI provider known as the WDM provider.
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.
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.
The sound card Sound Blaster AWE32 PNP CT3990 had a Plug-and-Play ISA Bus interface chip (large square chip, mid of bottom row).. The term Legacy Plug and Play, [1] also shortened to Legacy PnP, [2] describes a series of specifications and Microsoft Windows features geared towards operating system configuration of devices, and some device IDs are assigned by UEFI Forum.

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.
Virtual Audio Cable is a software product based on WDM multimedia driver that allows a user to transfer audio streams from one application to another. Any application is able to send an audio stream to the input side of a "virtual cable" while a corresponding application can receive this stream from the output side.
