Windows 1.0 Beta Release

Windows 1.0 Beta Release is a pre-release build of Windows 1.0 compiled on 1985-05-08. It includes an updated RTM-like 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 separate package called the "Software Development Kit" (SDK).

This build was possibly also released for various non-PC-compatible machines, such as Zenith Z-100 and RM Nimbus PC-186, but this has not been confirmed yet.

Installation
Before you run setup, it is recommended to create the directory you want Windows to be installed to, as there is a chance that setup fails to create the directory. For high-resolution color EGA mode, select "Enhanced Graphics Monitor with Enhanced Display" during Setup.

This beta will run on the following operating systems: For MS-DOS 5.0 or 6.x, run:  before loading Windows. For DOSBox, run. Failure to do this can result in the build crashing on startup.
 * MS-DOS 2.x / 3.x / 5.0 / 6.x
 * PC-DOS 2.x or 3.x
