Don’t let the name fool you. The latest Windows SDK for developing on Windows XP or Windows Server 2003 is the Microsoft Windows Software Development Kit Update for Windows Vista, released in March, 2007. Read more about it in this Windows SDK Team blog post or download it from the links below. The Windows SDK Update for Vista has the content needed to develop on or for Vista, but also supports creating applications for or on Windows XP, Windows Server 2003 SP1, and Windows Server 2003 R2. You can also create applications for Windows Server 2000 with this SDK, although development on Windows 2000 is not supported; in fact SDK installation on Windows Server 2000 is blocked.
