在没有 WDK 的情况下说风凉话？

Officially, you can't. But someone's been extracting them for your convenience and hosting them.

Note: You can get the older releases on the official site, but the latest ones are part of the WDK.

If you run winsdk_web.exe from the following link, you can selectively install windbg or extract windbg installer msi.

Microsoft Windows SDK for Windows 7 and .NET Framework 4 http://go.microsoft.com/fwlink/?LinkID=191420

Actually, Microsoft has now made the Debugging Tools downloadable separately from the SDK. Look for the section "Standalone Debugging Tools for Windows (WinDbg)" about mid-page:

• for Windows 8.1

• for Windows 10

If you're on Windows 7 x64, the solution provided by Sukesh doesn't work.

I managed to install the debugging tools by downloading the Windows SDK installer for Windows 8 (here), and then choosing "Debugging Tools for Windows" in the installer:

Try the MSDN archive link at http://archive.msdn.microsoft.com/debugtoolswindows/Release/ProjectReleases.aspx?ReleaseId=4912. It has the WinDbg MSI for both 32- and 64-bit (Version 6.12.2.633).

The standalone MSI file of windbg can be downloaded from here. The version is 6.12.0002.633 (x86). http://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C8E5D34E3D/setup/WinSDKDebuggingTools/dbg_x86.msi

For Windows 7 x86 you can also download the ISO: http://www.microsoft.com/en-us/download/confirmation.aspx?id=8442

And run \Setup\WinSDKDebuggingTools\dbg_x86.msi

WinDbg.exe will then be installed (default location) to: C:\Program Files (x86)\Debugging Tools for Windows (x86)

I found both, x64 and x86 version 6.12.0002.633 here:

http://rxwen.blogspot.de/2010/04/standalone-windbg-v6120002633.html

http://codemachine.com/downloads.html

Has all the individual msi files

You can also get it from Chocolatey:

https://chocolatey.org/packages/windbg

The saga continues with the Windows 10 version. I had to install Win Debug Tools on clean Windows 10 OS with Visual Studio 2015.

To make a long story short, just follow the instructions in the link provided by David Black. After downloading the files, instead of running the SDK installer, browse to the installers directory and execute the msi files directly.

I wonder how many man hours have been lost through the last decade because of MS sloppiness in regards to WDK/SDK installation?

This Microsoft link allows you to select the SDK. When you run the install and only select Windows debugging tools it will only download 288mb and install the tool as stand alone.

WinDbg is now available separately via MS Store. It's called "Preview" but I tested it to analyse some memory dumps and it works fine.

If you're on Windows 10 - launch MS Store, type "WinDbg" in the search box and voi-la - you have it. The download is approx. 100mb. It will downlaod required symbols automatically.

I was looking for the same thing for a quick operation and found this question. I needed both 32-bit and 64-bit versions.

This is an older version but the links are from the Microsoft servers, it should be safe. The link for 32-bit version is also in a previous answer but the version number i get on the install is different, maybe the same link is updated with a newer version since 2013.

Cheksums are generated both locally and on VirusTotal, they match.

I tested the 64 bit debugger with a 64 bit program that was compiled some years ago (~2012) and it works. Test is done on Windows 10 Pro 64 bit (v2004 Build 19041.207).
