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.
User-Mode Driver Framework (UMDF) is a device-driver development platform first introduced with Microsoft's Windows Vista operating system, and is also available for Windows XP. It facilitates the creation of drivers for certain classes of devices.
Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM. [4] With the removal of XDDM from Windows 8, however, WDDM became the only option. [5] WDDM provides the functionality required to render the desktop and applications using Desktop Window Manager, a compositing window manager running on top of Direct3D.
Because of these issues, Microsoft has released a new set of frameworks on top of WDM, called the Windows Driver Frameworks (WDF; formerly Windows Driver Foundation), which includes Kernel-Mode Driver Framework (KMDF) and User-Mode Driver Framework (UMDF). Windows Vista supports both pure WDM and the newer WDF. KMDF is also available for ...
Windows Vista is a major release of the Windows NT operating system developed by Microsoft.It was the direct successor to Windows XP, released five years earlier, which was then the longest time span between successive releases of Microsoft Windows.
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.
Starting with Windows Vista, the primary client component became Windows Update Agent, an integral component of the operating system. The service provides several kinds of updates. Security updates or critical updates mitigate vulnerabilities and security exploits in Microsoft Windows.
A new user-mode driver model called the User-Mode Driver Framework. In Windows Vista, WDDM display drivers have two components, a kernel mode driver (KMD) that is very streamlined, and a user-mode driver that does most of the intense computations. With this model, most of the code is moved out of kernel mode.
