Symbols for the Windows debuggers (WinDbg, KD, CDB, and NTSD) are available from a public symbol server. You can also download entire symbol packages.
This section includes:
Accessing Symbols for Debugging
How the Debugger Recognizes Symbols
Symbol Problems While Debugging
These topics explain what symbols are, how to access them during a debugging session, how to control the debugger's symbol options and symbol matching, and how to respond to various symbol-related problems during debugging.
If you simply want to configure your debugger to access symbols for your own programs and for Windows, you may find it quicker to read the less-detailed introductory topics Symbol Path and Using a Symbol Server.
