Windows 95 build 81

Windows 95 build 81 is a milestone 5 build of Windows 95. It's the earliest leaked build to have a single Start button and menu enabled by default (though builds 73f and 73g also have it, it's disabled). It's also the earliest leaked build to have the now ubiquitous close button on the right side of window titlebars.

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, identical to builds 73f and 73g.
