Windows 1.0 1983-11-20 build

Windows 1.0 "L'Ordinateur Individuel" builds were two builds of Windows 1.0 from 1983 found in the French computer magazine L'Ordinateur Individuel. There are 10 high resolution close-up photos of the two builds circulating on the internet. The exact compilation date was unknown but it was believed to be compiled around 1983/11/20 same as Microsoft Windows "Monthly ASCII" build.

Why 2 builds
The photos can be grouped into 2 sections, one with date on the status bar and one with blank status bar. 2 out of the 10 photos have date and build number on the status bar and the rest doesn't. It is currently unknown whether they came from the same build or not so it is only an assumption that the photos came from 2 different builds.

Applications
The photos were high resolution which is rare for such builds so there could be more details. It is quite clear to see the applications running and they were: Art, Calendar, Clock, MS-DOS, Spread Sheet, Text. A01.PIC was the famous Microsoft I picture and TEXT.TXT was the Heuristic Reasoning text seen many demo builds. A02.PIC however is not the Microsoft II picture, it is a picture possible made by L'Ordinateur Individuel for demonstration purposes.

MS-DOS
The MS-DOS shell in this version of Windows was very primitive, it looks like COMMAND.COM but is actually the shell of this build like MS-DOS Executive in later and RTM releases. It accept,  ,  ,  ,   and   commands. Those commands are equivalent to,  ,  ,  ,   and   in MS-DOS. The ability to run MS-DOS apps was not implanted until Alpha release in January 1985.

The status bar
The status bar in the first build shows  suggesting the compilation date. The status bare in the second build is mostly white except for when resizing a window, it shows  which could suggest clicking both buttons using your mouse will cancel the resize. The help icon was not on the status bar and by clicking the icon at the top right corner you will have the options to set, to   and to.

File list
Files shown:
 * : Sample images displayed by the Art application.
 * : MS-DOS or PC DOS 2.x system files. It suggests this build might have been a bootable demo disk or installed to hard drive in the same directory as DOS.
 * : Plain text file used by the Calendar application.
 * : Microsoft Windows Input/Output Driver.
 * : Cursor used by Windows.
 * : The main Windows executable, possibly used to start Windows. It was still used in starting DR5 although replaced by a batch file with the same name.
 * : Font used by Windows.
 * : Icon used by Windows, possibly the MS-DOS Executive icon.
 * : Probably a resource file used by Windows. The extension might suggest it was a pattern file or related to patterns.

Missing files
The executable of Art, Calendar, Clock, Spread Sheet and Text was not seen in the file list, suggesting they might have been on a separate disk.
