Download Debugging Tools for Windows
The Windows Debugger (WinDbg) can be used to debug kernel-mode and user-mode code, analyze crash dumps, and examine the CPU registers while the code executes.
To get started with Windows debugging, see Getting Started with Windows Debugging.
Download WinDbg Preview
WinDbg Preview is a new version of WinDbg with more modern visuals, faster windows, and a full-fledged scripting experience. It is built with the extensible object-orientated debugger data model front and center. WinDbg Preview is using the same underlying engine as WinDbg today, so all the commands, extensions, and workflows still work as they did before.
Download WinDbg Preview from the Microsoft Store: WinDbg Preview.

Adding the Debugging Tools for Windows if the SDK is already installed
If the Windows SDK is already installed, open Settings, navigate to Apps & features, select Windows Software Development Kit, and then select Modify to change the installation to add Debugging Tools for Windows.
Looking for the debugging tools for earlier versions of Windows?
To download the debugger tools for previous versions of Windows, you need to download the Windows SDK for the version you are debugging from the Windows SDK and emulator archive. In the installation wizard of the SDK, select Debugging Tools for Windows, and deselect all other components.
