[2] Debugging is the process of finding and resolving errors in a system; in computing it also includes exploring the internal operation of software as a help to development.
Like the Visual Studio Debugger, WinDbg has a graphical user interface (GUI), but is more powerful and has little else in common.
[5] WinDbg can also be used for debugging kernel-mode memory dumps, created after what is commonly called the Blue Screen of Death which occurs when a bug check is issued.
[7] WinDbg is distributed as a standalone package from the Windows Debugger Portal and via the Microsoft Store.
[9] TTD allows a user to record an actual live process (at a performance penalty) to later debug going back and forth in time.
In addition, WinDbg has updated user interface, support for dark mode and keyboard navigation.
[10][11] WinDbg allows the loading of extension DLLs[12] that can augment the debugger's supported commands and allow for help in debugging specific scenarios: for example, displaying an MSXML document given an IXMLDOMDocument, or debugging the Common Language Runtime (CLR).
Ext is a standard Windows Debugger extension that ships with WinDBG and is loaded by default.
WinDbg allows debugging a Microsoft Windows kernel running on a virtual machine by VMware, VPC or Parallels using a named pipe.
