Microsoft Windows Software Development Kit (SDK) provides the documentation, samples, header files, libraries, and tools you need to develop applications that run on Windows. The applications you develop with this edition of the SDK can run on the x86, x64, and Itanium-based versions of Windows Server 2003 SP1, Windows XP SP2, Windows XP x64 Pro Edition, and Windows 2000. A new custom install allows you to select components you wish to install on a more granular level.
This edition of the SDK replaces the previous SDKs for Windows XP SP2 and Windows Server 2003 and can be used to develop applications for those platforms. This version is the first release on CNET Download.com.
