Summary of Debugger Extensions in Wdfkd.dll

The Windows Driver Kit (WDK) includes a debugger extension library, named Wdfkd.dll. This library contains debugger extension commands that you can use to debug both Kernel-Mode Driver Framework (KMDF) and User-Mode Driver Framework (UMDF) drivers starting with version 2.

For a complete description of each command, see Windows Driver Framework Extensions (Wdfkd.dll). For more information about all available debugger extension libraries, see the documentation that is supplied with the Windows Debugging package.

You can find a video series that demonstrates how to debug a KMDF driver at Videos: Debugging KMDF Drivers.

To debug a driver that uses UMDF version 1.11 or earlier, you must instead use the Wudfext.dll debugger extension library. For more info, see User-Mode Driver Framework Extensions (Wudfext.dll).

The extension commands that the Wdfkd.dll extension library provides include:
