It is still unclear whether this is a Windows 2000 post-RTM build or an Alpha build of Windows XP (codename Whistler). The "SD" in the build tag refers to a new code management system that Microsoft was using ("Source Depot") at the time. This build seems likely to have been compiled as a test of this system. Some people think that this build is mentioning Whistler at the beginning of the Setup Process, but that was because of a fix for the BSOD at the beginning of setup.
