See below for a more indepth description of Windows. This is Windows 1.01, circa late 1985. 512k RAM, 10m hard drive, 8088-5mHz processor, IBM Color Graphics Adapter and 5153 color monitor, and IBM DOS 3.1. The windows are tiled, they do not overlap. The MS-DOS Executive is used to manage files, as well as start applications.
Paint is a monochrome program.
You can cut from Paint and paste into Write, using the clipboard, just like in newer versions. The commands are very limited, though, and no online help. Reversi is included for entertainment. When used with a better graphics adapter and monitor, such as EGA, Windows 1.01 is in color. This is Windows 1.03, from August 1986.
