Windows Neptune Build 5111.iso -
The user interface of Build 5111 is a study in evolution. While the core aesthetic remains the polished, professional look of Windows 2000, Neptune introduced a new "Watercolor" visual style (a precursor to the famous "Luna" style of Windows XP) and a redesigned Start menu. The Start menu in Neptune notably incorporated a "Log Off" button and distinct user profile switching—features that were revolutionary for the time but are now standard. This hinted at an OS designed for a family setting, where a single home computer might have multiple users with personalized settings, a stark contrast to the single-user chaos of Windows 98.
