Symbols 2.0

The symbol download packages are classified by processor type (x86, Itanium, and x64) and build type (retail and checked). Most customers need the symbols for the retail version. If there is a special version of Windows with additional debugging information, then the symbols for the checked version should be downloaded. Windows XP and later and Windows Server 2003 and later do not need localized symbols to debug localized versions of the product. Each symbol download package for these versions of Windows can be used to debug all localized versions.
