Windows NT 3.1 build 404.1
|Build of Windows NT 3.1|
Windows NT 3.1 build 404 is the 1993-03 beta of Windows NT 3.1. This build now uses a setup that's closer to the one in RTM. Alongside, new applications like Mail, Schedule+, and new Regedit have been added. This is the first build with a default color scheme based on the one in Windows 3.1 instead of Windows 3.0 like in previous builds.
