This latest version features a more modern user experience with an updated interface, fully fledged scripting capabilities, an extensible debugging data model, built-in Time Travel Debugging (TTD) support, and many additional features.

For more information, see WinDbg Overview.

Select Install and the debugger will download and install.

WinDbg will also periodically check for new versions in the background and autoupdate if necessary.


Formerly released as WinDbg Preview in the Microsoft Store, this version leverages the same underlying engine as WinDbg (classic) and supports all the same commands, extensions, and workflows.

To get and stay on the latest release, install WinDbg as described on this page. WinDbg Preview will not receive further updates in the Microsoft Store.

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.
