DOSBox is a free and open-source emulator which runs software for MS-DOS compatible disk operating systems—primarily video games. [5] It was first released in 2002, when DOS technology was becoming obsolete.
NTVDM from ReactOS, the custom standalone variant of NTVDM by Michael Stamper (able to run windowed text mode MS-DOS software in 64 bit Windows NT systems, this NTVDM works by using the following syntax: ntvdm.exe program.exe, like start command in Windows. MS-DOS Player for Win32-x64, a Microsoft MS-DOS Emulator, runs many command line DOS ...
It can thus achieve nearly native speed for 8086-compatible DOS operating systems and applications on x86 compatible processors, and for DOS Protected Mode Interface (DPMI) applications on x86 compatible processors as well as on x86-64 processors. DOSEMU includes an 8086 processor emulator for use with real-mode applications in x86-64 long mode.
Tao ExDOS enables users of DOS applications to work with these applications on new operating systems. Using the built-in Virtual 8086 mode of the x86 CPU, Tao ExDOS enables DOS and 16-bit Windows applications (that run under DOS) to run effectively in 32-bit Windows desktop environments, including Windows 10/8/7/Vista/XP/2000 and Windows Terminal Server 2003/2008.

dbDOS VM Virtual Machine (dbDOS VM); The dbDOS VM or VM stands for Virtual Machine and with dbDOS it is a DOS emulation that allows products developed for DOS-based applications to run inside the virtual machine. The VM supports the Windows Operating Systems (XP, 2003, Vista, 2008, 7, 8, 8.1) in either 32- or 64-bit editions.
MESS, an emulator for many video game consoles and computer systems, based on the MAME core, was integrated into MAME in 2015. With OTVDM (WineVDM) a version of MAME is available to emulate 16-Bit DOS and Windows applications on x64 and AArch64 versions of Windows. The NTVDM from Microsoft is only supported for the 32-bit versions of Windows.
In all 32-bit (IA-32) editions of the Windows NT family since 1993, DOS emulation is provided by way of a virtual DOS machine (NTVDM). 64-bit (IA-64 and x86-64) versions of Windows do not support NTVDM and cannot run 16-bit DOS applications directly; third-party emulators such as DOSbox can be used to run DOS programs on those machines.
Villani had already been working on a DOS-like operating system for use in embedded systems for some while before the advent of FreeDOS. [2]His efforts started when he developed an MS-DOS 3.1-compatible interface emulator to write device drivers in the C high-level language instead of in assembly language, [3] as was the usual approach at that time.
