Windows Driver Frameworks

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 NT. It complements Windows Driver Model, abstracting away much of the boilerplate complexity in writing Windows drivers. Windows Vista and later are included WDF natively; for Windows 2000 and Windows XP, the WDF update is available.
