The Windows Driver Kit (WDK) is a software toolset from Microsoft that enables the development of device drivers for the Microsoft Windows platform.

[2] It includes documentation, samples, build environments, and tools for driver developers.

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.

The WDK 8.x and later series goes back to require installing a matched version of Visual Studio separately, but this time the integration is more complete in that you can edit, build and debug the driver from within Visual Studio directly.
