Windows 1.0 Beta Release

Windows 1.0 Beta Release is a pre-release build of Windows 1.0. It was compiled on 1985-05-08. This build includes an updated RTM-style installer, mostly finalized UI, color support on the IBM PC and additional applications, alongside redesigns of existing ones from the Alpha. Source code and documentation for the developers was moved to a sepparate package called the "Software Development Kit" (SDK).
