Windows XP build 2202

The "SD" in the build tag refers to a new code management system that Microsoft were using ("Source Depot") at the time. This build seems likely to have been compiled as a test of this system. It is still unclear whether this is a Windows 2000 post-RTM build or an Alpha build of Windows XP (codename Whistler). During the installation process, only in the beginning it refers itself as Windows Whistler.
