Windows 3.1 build 071

Windows 3.1 build 071 is a build of Windows 3.1. It is listed in a French Microsoft Knowledge Base article. It is also mentioned several times in an internal Microsoft document from February 1992.

The KB article describes an issue when Word for Windows 6.0 is started on this build - a general protection fault (GPF) is encountered in. This issues also happens on builds 068 and 070, and potentially other builds from that range, according to the article. A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program. The mechanism is first described in Intel manuals and datasheets for the Intel 80286 CPU, which was introduced in 1983; it is also described in section 9.8.13 in the Intel 80386 programmer's reference manual from 1986. A general protection fault is implemented as an interrupt (vector number 13 (0Dh)).

According to the internal document, several third-party applications were tested on this build.
