Microsoft Windows Symbol Packages

Microsoft has released some new Symbol Packages for Windows:

If you want the entire set of symbols for Windows® .NET Server, Windows XP, or Windows 2000, then you can download a symbol package and install it on your computer.

The symbol download packages are listed by processor type (x86 and Intel® IA-64) and build type (retail and checked). Almost all customers require the symbols for retail products. If you are debugging a special version of Windows with extra debugging information, then you should download the symbols for the checked version.

Windows XP and Windows .NET Server do not require localized symbols in order to debug localized versions of the product. Each Windows XP and Windows .NET Server symbol download package works for debugging all localized versions.
