Two editions of Windows 2.10 were released;
Windows/286 and Windows/386, both of which
could take advantage of the Intel processor for
which they were designed.
Despite its name, Windows/286 was fully
operational on an 8088 or 8086 processor.
Windows/286 would simply not use the high
memory area since none exist on an 8086-class
processor; however, EMS could still be used, if
present. A few PC vendors shipped Windows/286
with 8086 hardware; an example was IBM's PS/2
Model 25, which had an option to ship with a
"DOS 4.0 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.
