 * Not to be confused with Windows 3.0 build 55.

Windows 3.1 build 055 is an unleaked build of Windows 3.1, mentioned in internal Microsoft e-mails from December 1991.

The e-mail claims this build loads native Windows applications twice as fast as OS/2 2.0 build 6.167 loads Presentation Manager applications or Windows applications in a "Windows box".
