In fact, DOS games are fully supported on Windows until 98/ME and will work on most later 32-bit versions, while they are fully supported on all OS/2 versions and their successor eComStation (2001).

Both can be used on Windows (1985) or OS/2 (1987) because Microsoft was involved in writing both operating systems. The EXE files are a type (MZ) native to MS-DOS.

The COM files are an older format used by an early operating system called CP/M, and since MS-DOS derived from a clone of CP/M it also used the COM extension but made its COM files incompatible. MS-DOS games are 16-bit programs which are either COM or EXE files. Microsoft published Windows Minesweeper in October 1990 so DOS versions are not historically important except for the fact a different DOS game called Relentless Logic inspired the creation of Minesweeper. DOS refers to a group of similar operating systems with the most famous being MS-DOS (1981) by Microsoft, which was sold as PC-DOS on IBM computers. This is a collection of minesweeper games for DOS.
