Getting started with WinDbg

To get started with WinDbg, see Getting Started with Windows Debugging.

To get started with debugging kernel-mode drivers, see Debug Universal Drivers - Step by Step Lab (Echo Kernel-Mode). This is a step-by-step lab that shows how to use WinDbg to debug Echo, a sample driver that uses the Kernel-Mode Driver Framework (KMDF).

To debug older versions of Windows, use WinDbg (classic) available with Debugging Tools for Windows.
