This build was branded as (in the screensaver) as being Microsoft Windows Whistler 2001. It still is branded in WINVER.EXE as Windows 2000 but it's called "Windows Whistler Professional." It did not contain the watercolor theme. This was the first build to have a new logon screen, albeit in a very early stage.
