Windows 2.0 was the second release of the Microsoft Windows enviroment for MS-DOS. It was not a commercial sucess, however it furthered the development of the kernel so that it could use XMS memory, and it later introduced a 286 specific version that could do some limited multitasking with MS-DOS, and a 386 specific version that could spawn multiple VDM's.
It was superceded by Windows 3.0.
Windows/286
This version had some specific code to the 80286 cpu allowing limited MS-DOS multitasking. However since each instance of MS-DOS consumed the same limited 640kb memory pool, it was largely ineffective.
Windows/386
Windows/386 was Microsoft's first product to allow people to directly use the V86 mode of the 80386 cpu. With enough expanded memory you could run several virtual MS-DOS machines.
