Windows 2.0 April 1987 build

The Windows 2.0 April 1987 build is the earliest known build of Windows 2.x, shown in the May 1987 issue of the 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 inside the Calendar program, meaning it was likely compiled on or slightly before that date. Another screenshot also displays "This is Windows 2.00" in Write, possibly meaning the screenshots belong to that version.
