Windows XP build 2197

Build 2197 was compiled in early 2000. There is an ongoing dispute on whether is this a post-RTM build of Windows 2000 build or a very early build of Windows XP. BuildFeed lists this build in a Windows 2000 category. However, in an IT Pro article from 2000-02-13 Paul Thurrott claimed that build 2197 was the first internal build of Whistler and that it had gone out "weeks ago".

This build's build tag suggests that this build, if existent, could be one of the first builds compiled using Microsoft's new Source Depot version control system.
