Windows 95 build 81

Windows 95 build 81 is the earliest leaked build of Windows 95 to have a single Start button and menu enabled by default (though builds 73f and 73g also have it, it's disabled). While the build itself is real, some copies found online are said to have a modified boot screen saying "January 1994". The unmodified copy still has the "November 1993" boot screen, same as builds 73f and 73g.
