Changes
This build offered many changes in the GUI. For one, this build intruduced the Visual Styles, the first bite at the GUI technology of Windows XP. This build featured the Professional theme, which was later replaced by an another theme. This build also featured a completely changed HTML webview, including a task-based Control Panel.

Microsoft was quietly working on several hidden features. One of them being the Start Panel, an unlockable feature. It was going to be a replacement for the classic start menu. This build also featured a hidden active desktop-based Start Page, continuing the work started in Neptune.
