Windows NT 3.1 build 265 is an unleaked build of Windows NT 3.1, mentioned in the file UTILS.C from the Windows NT 4.0 source code.

Note:          This function originally used the runtime div function
               instead of (/ and %), but the div runtime function is
               now broken (build 265).

It's also mentioned in the file TIME.C, the date in which suggests this build may have been compiled in May 1992.
