Windows NT 3.1 build 404

Windows NT 3.1 build 404 is the March 1993 beta. This build now has been updated to use a setup that is close to the RTM's. Alongside, new applications like Mail, Schedule+, and new Regedit has 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.
