Windows Nashville build 999

Windows Nashville build 4.10.999 is the only leaked build of Windows codename Nashville. Installation is similar to installing an upgrade version of Windows 95. Contains Athena PIM (later Outlook). This build still contains many references to Windows 95, though it is mentioned as Windows 96 in Add/Remove Programs and Windows Nashville in the ver command.

It does not always work and may BSOD during the second stage of setup.
