A modified version of Windows runs in the so-called System VM, a special virtual machine that controls the VMM and has access to all I/O devices by default. Both Windows and MS-DOS applications could also make use of [[w:Expanded memory|EMS]] emulation provided by the virtual machine manager. However, swap is not supported and all running applications therefore have to fit into physical memory.

The original version was renamed to Windows/286 starting with version 2.1, which added the ability to use the [[w:High memory area|high memory area]] (HMA) for an additional 64 KB of conventional memory with a [[w:Intel 80286|286]] processor, although it does not necessarily require one and still runs on the original 8086 and 8088. The separate 386 variant was discontinued with Windows 3.0, which includes its functionality in the 386 Enhanced mode. The new Standard mode also carries over some of the MS-DOS support improvements, such as grabber files.
