Windows/286 2.10 and Windows/386 2.10 launch

Windows/286 with 8086 hardware is an example was IBM's PS/2 Model 25, which had an option to ship with a "DOS 4.00 and Windows kit" for educational markets, which included word processing and presentation software useful for students, which resulted in some confusion when purchasers of this system received a box labeled Windows/286 with a machine that was definitely less than an 80286.

Windows/386 was much more advanced than its predecessor. It introduced a protected mode kernel, above which the GUI and applications run as a virtual 8086 mode task. It allowed several MS-DOS programs to run in parallel in "virtual 8086" CPU mode, rather than always suspending background applications.
