Windows 2.0

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It was superceded by Windows 3.0.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/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.
