Debugging Tools for Windows (WinDbg, KD, CDB, NTSD)
Start here for an overview of Debugging Tools for Windows. This tool set includes WinDbg and other debuggers.
- As part of the WDK
Install Microsoft Visual Studio and then install the Windows Driver Kit (WDK). Debugging Tools for Windows is included in the WDK. You can get the integrated environment here.
- As part of the Windows SDK
Install the Windows Software Development Kit (SDK). Debugging Tools for Windows is included in the Windows SDK. You can get the Windows SDK here.
- As a standalone tool set
If you want to download only Debugging Tools for Windows, install the Windows SDK, and, during the installation, select the Debugging Tools for Windows box and clear all the other boxes.
These are the default installation directories for Debugging Tools for Windows:
- C:\Program Files (x86)\Windows Kits\8.x\Debuggers\x64
- C:\Program Files (x86)\Windows Kits\8.x\Debuggers\x86
After you install Visual Studio and the WDK, you'll have six available debugging environments. All of these debugging environments provide user interfaces for the same underlying debugging engine, which is implemented in dbgeng.dll. This debugging engine is called the Windows debugger, and the six debugging environments are collectively called the Windows debuggers.
Note Visual Studio includes its own debugging environment and debugging engine, which together are called the Visual Studio debugger. The Visual Studio debugger is completely different from Windows debugger.
The Windows debuggers can run on x86-based, x64-based, or ARM-based processors, and they can debug code that's running on x86-based, x64-based, or ARM-based processors. Sometimes the debugger and the code being debugged run on the same computer, but other times the debugger and the code being debugged run on separate computers. In either case, the computer that's running the debugger is called the host computer, and the computer that is being debugged is called the target computer. The Windows debuggers support the following versions of Windows for both the host and target computers.
Windows 8.1 and Windows Server 2012 R2
Windows 8 and Windows Server 2012
Windows 7 and Windows Server 2008 R2
To debug code running on Windows Vista, Windows Server 2008, Windows XP or Windows Server 2003, get the Windows 7 Debugging Tools for Windows package, which is included in the Microsoft Windows Software Development Kit (SDK) for Windows 7 and .NET Framework 4.0. If you want to download only Debugging Tools for Windows, install the SDK, and, during the installation, select the Debugging Tools for Windows box and clear all the other boxes.
Note You might have to uninstall Microsoft Visual C++ 2010 Redistributable components before you install the SDK. For more information, see the Microsoft Support website.
In addition to the debuggers, Debugging Tools for Windows includes a set of tools that are useful for debugging. For a full list of the tools, see Tools Included in Debugging Tools for Windows.
