Windows 2.0 April 1987 build

Windows 2.00 is the earliest known build of Windows 2.x, shown in the May 1987 issue of Microsoft Systems Journal magazine.

The user interface now features overlapping windows alongside new windowing controls, and still retains the color scheme from Windows 1.0. One screenshot shows a date of 20 April 1987, meaning it was likely compiled on or slightly before that date.
