The WinDbg debugger is a powerful, graphical tool that allows you to debug Win32-based applications on Windows NT and Windows 95. You can also use the integrated text editor to edit your source code.
Windows NT: You can also use WinDbg to debug service applications and kernel-mode drivers.
Note To debug a 16-bit application, use a 16-bit debugger, such as the one included in Microsoft Visual C++ version 1.5.
The WinDbg files are installed when you install the developer tools included with the Platform SDK. For information on using WinDbg, see the help file windbg.hlp, which is included with WinDbg.
