Windows NT 3.1 build 438
|Build of Windows NT 3.1|
|Architecture||x86, MIPS, Alpha AXP|
Windows NT 3.1 build 438 is the April 1993 beta of Windows NT 3.1. It is not much different from the previous build, which was released a month earlier. A version of the build in the Alpha AXP architecture was shared on 4 August 2020.
This build was mentioned in an internal Microsoft e-mail from August 1993 where it states that it was delivered to Novell in order to test their NetWare Client for the then-upcoming NT operating system, highlighting the issue that further recompilations of the aforementioned software had failed to work properly. The e-mail also states that Novell had received the June 1993 beta three weeks later than what was originally promised by Microsoft.
