Windows 3.1 build 068

Windows 3.1 build 068 is a Release Candidate build of Windows 3.1. The build is mentioned in an internal Microsoft document from February 1992 and is listed in a French Microsoft Knowledge Base article. The real build was later leaked to BetaArchive on 24 November 2017. The leak was modified by the original leakers from a warez group called WARES, which changed some strings in  and modified file dates.

This is also the first build that removes the "Reboot Windows" button at the end of Setup. The tutorial has now been placed at the end of the Setup. Task Manager features full-screen warnings that resemble a BSOD (in this build they are black) that are nearly identical to the ones used in the RTM. According to Andrew Schulman's article titled Examining the Windows AARD Detection Code from 1 September 1993, this build contained the infamous AARD code (build 061 is also said to contain it) and was labeled as "pre-release build 3.10.068" and dated 21 January 1992. This build is also the first to include the boot screen used in the RTM release.

Anti-trust document
The document only says this build was released to testers on 24 January 1992.

Microsoft KB article
The French 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 070 and 071, and potentially other builds from that range according to the article.

Fake build
A heavily modified copy of this build originated from community member betaguy224 and was later leaked by Battler. The build was eventually declared to be fake, as it combined files from the real build 068 mixed into other builds, and was removed from the BetaArchive FTP server in July 2013. This copy can still be found online.
