Windows 2000 build 1515.1 is the earliest leaked build of Windows 2000. This build introduces many features originally found in the Microsoft Cairo project, most notably Distributed File System, CairOLE (OLE) and CSCRIPT.EXE, a new user interface provided by the Windows Desktop Update as well as many user accessibility improvements which have been a key part of Windows 2000's development. It also includes Plug and Play driver support, Windows Installer support, and the Microsoft Management Console.
Some server components are present on this build installation media, along with the build binary output logging files, which means that the build was leaked directly from the build machine output folder at Microsoft.
