Microsoft Windows 2.03 appears to only marginally different from 1.01, sporting a higher resolution and more colourful graphics. 

Unlike previous versions, this iteration of Windows will work with DOS 5.x and later.

The files for Microsoft Windows 2.03 was made available to me by someone on IRC. I've turned them into separate WinImage-compatible disk images and put them into a single ZIP file.

Tested on:
486DX2/66 w/16MB RAM and MS-DOS 6.22
