A further ICL/MS MS-DOS 4.10.30 version was released on May 10, 1988. No further releases were made once the contracts had been fulfilled. In July 1988, IBM announced " IBM DOS 4.0 ", an unrelated product continuing from DOS 3.3 and 3.4 , leading to initial conjecture that Microsoft might release it under a different version number.

Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
A similar model is used in Windows 9x and the Windows NT family, where native 32-bit applications are multitasked preemptively. [10] 64-bit editions of Windows, both for the x86-64 and Itanium architectures, no longer support legacy 16-bit applications, and thus provide preemptive multitasking for all supported applications.

It was widely thought to be the first program to bring multitasking and windowing capabilities to DOS; in fact, there was a predecessor, IBM TopView, which shipped March 1985. [3] Under DESQview, well-behaved DOS programs can be run concurrently in resizable, overlapping windows (something the first version of Windows cannot do).
Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers.. An evolution of the older Concurrent CP/M-86, Concurrent DOS and Concurrent DOS 386 operating systems, it was originally developed by Digital Research and acquired and further developed by Novell in 1991.
A 3 GHz model of the Intel Pentium 4 processor that incorporates Hyper-Threading Technology [7]. Hyper-Threading Technology is a form of simultaneous multithreading technology introduced by Intel, while the concept behind the technology has been patented by Sun Microsystems.
