NTVDMx64 by Leecher1337
A verson of NTVDM for 64-bit Windows
NTVDMx64 makes it possible to run old DOS applications under 64-bit Windows 7 and Windows 10. (It is reported to work correctly with Windows Server 2008 R2, and perhaps also with more recent Windows Server versions.)
Recent versions of NTVDMx64 make it possible to run 16-bit Windows applications under 64-bit Windows, but you may prefer to use the much less obtrusive otvdm/winevdmfor this purpose.
Unlike emulator applications such as vDos and DOSBox, NTVDMx64 is fully integrated with Windows, with the same access to the Windows file system and ports that NTVDM has under 32-bit Windows. NTVDMx64 does not perform as quickly as DOSBox or vDos, but its integration is a unique and important advantage. For example, a DOS application running under NTVDMx64 can print directly to LPT1 if the computer has a parallel port; this is impossible under DOSBox (although possible with vDos through a configuration option).
NTVDMx64 is not my work! It is a patched version of Microsoft's original NTVDM, based on the leaked source code of Windows NT, and patched by a programmer who calls himself 'Leecher1337.' The leaked source code may not be distributed legally, so, in order to avoid legal problems, Leecher1337 publishes only patch files that contain modifications to the original code. These patch files may be downloaded from his GitHub page. With the proper development environment, the patched Windows NT code can be compiled to build a 64-bit version of NTVDM, which Leecher1337 has named NTVDMx64.
Leecher1337 does not distribute a compiled version of his patched version, but I have obtained a copy, together with an installer, which may be downloaded here (in versions for sixteen languages). I did not build this copy; I obtained it from another source. To install NTVDMx64, run INSTALL.BAT, and restart your system when prompted. If you want, you may uninstall it from the Control Panel or PC Settings. This installer is frequently updated to match the latest version of Leecher1337's code. (Updated October 2020.)
Warning:If Microsoft asks me to take down this page for any reason at all, the page and all files linked from it will be deleted immediately. Microsoft has not made any such request during the years that this page has been posted.
All comments and questions about NTVDMx64 should be posted on Leecher1337's Github page.Do not waste your valuable time sending me e-mails asking for help installing and running NTVDMx64, because I will not know the answers. Open an issue at the GitHub page for this project.
NTVDMx64 cannot run if the 'secure boot' feature is enabled on your computer. If secure boot is enabled, the installer will warn you and refuse to run. You must disable secure boot in the BIOS settings of your machine; it is not a Windows setting. If you don't know how to accomplish this, search the web or consult the manual for your system board.
Windows Smart Screen may refuse to let the installer run; choose Run Anyway from the buttons that appear when you click on More Info (or some similar setting). Windows Defender may block a DLL in the program; find it in the Quarantine settings, click on its name, and choose Restore. Other anti-virus programs may similarly block the installation. Don't complain to me or to Leecher1337; complain to your anti-virus vendor. And don't waste your extremely valuable time asking me or Leecher1337 whether this software is unsafe. If you don't want to override these security features, don't use this software.
Cautions and warnings: NTVDMx64 uses non-standard methods of process propagation to inject loader code into 32-bit and 64-bit applications. I don't know exactly what this means, but I am reliably told that this may cause problems not yet recognized. You may want to experiment with a VMware or other virtual machine before running it on production systems. Also, it has been tested only under 64-bit Windows 7 and 64-bit Windows 10. Do not attempt to run it under any earlier version!
You may launch DOS applications from the Windows command prompt (CMD) or by double-clicking them in Windows Explorer. The first time you try to run any DOS program, you may see an error message; try again immediately afterwards, and the program should run.
Some programs will require command-line switches to run. For example, WordPerfect for DOS 6.x should be started with the /NE command-line switch. Some programs will not run at all; there is probably nothing that can be done about those programs, but you should feel free to file a very detailed 'issue' at the GitHub page linked above.
Microsoft's NTVDM uses a licensed version of the SoftPC emulation software by Insignia. The original NTVDM, written for Windows NT, operated differently when run on Intel's x86 hardware and on alternate hardware, including VAX VMS, DEC Alpha, and Mips. SoftPC included a software-based CPU (CCPU) that could emulate an Intel 80386 processor. For performance reasons, when running under an Intel processor, the emulated CPU was not used; instead, the V86 mode of the hardware CPU was used, via a kernel interface which Microsoft called 'Monitor'. So the CCPU was used only on non-x86 architectures, and the Monitor interface was used on x86. Leecher1337's NTVDMx64 modifies the original code so that the CCPU is used when running under 64-bit Windows, because Intel processors have no V86 support in the 'long mode' used by 64-bit Windows.
This copy of NTVDMx64 makes one change in the CONFIG.NT file from the original NTVDM: it increases the FILES = line from 20 to 100, which should be sufficient for most applications). If you want to change that number, or make any other changes in CONFIG.NT, do the following: run CMD.EXE as an administrator; navigate if necessary to WINDOWSSYSTEM32 and run the command 'start notepad config.nt', and edit the file.
For a full description, see Leecher1337's Github page, which also notes some problems with DPMI programs and DOS extenders.
Like NTVDM, NTVDMx64 can be customized from the system menu of an NTVDMx64 window to change window size, display font, etc. Unlike NTVDM, it switches smoothly between text and graphic modes.

Play DOS Games on Windows 10, Windows 8.1 and Windows 7 with DOSBox
The ultimate solution to play DOS games on your PC with Windows 10, Windows 8.1, 8, 7, Vista or XP is DOSBox. DOSBox emulates DOS and the environment in which DOS ran in the past (like an old pc), including memory management and sound configuration, but with the power of your computer today. On this page we'll show you how to make the classic DOS game Prince of Persia or any other DOS game work. You can also play Prince of Persia directly on Windows 10. If you want to install a DOS game from an original CD-rom, you can find instructions here.
Download and install DOSBox
Go to the download section on www.dosbox.com
Download the desired package (in this example that will be the Windows (win32) installer)
Install DOSBox
Download and extract Prince of Persia (or any other DOS game)
Go to one of the many websites that offer shareware and freeware downloads of classic DOS games, for example www.dosgames.com
Search for and download the desired game, in our example Prince of Persia
Create a new folder on your computer, for example C:gamesdosprince
Extract the downloaded zip file into that folder
Dosbox For Windows 8.1 64 Bit Free Download
Get the game working in DOSBox
Start DOSBox from Windows by double clicking the desktop icon. Once in DOSBox:
Download Dosbox 0.74 For Windows 8.1 64 Bit
Type in mount c c:gamesdos and press enter (this creates a virtual drive C: within DOSBox, which points to the GamesDOS folder on your local C: drive)
If your games folder contains spaces, you have to put quotes around the folder path, for example: mount c 'c:gamesdos games'
Type in c: and press enter to go the virtual C: drive
Type in dir and press enter to look at the contents of the virtual C: drive
Type in cd PRINCE and press enter to open the Prince folder
Type in PRINCE and press enter to start the game
Automatic mounting
As you always will need the virtual drive in DOSBox to play your game, it is recommended to put the mount command in your DOSBox configuration file. This way the games folder will be mounted automatically when you start DOSBox:
Open the configuration file:
Windows 7: Press CTRL + ESC (or click the start button), type in dosbox and the options file should appear in the search results, click it
Windows 8: Press the Windows key + Q, type in dosbox and the options file should appear in the search results, click it
Scroll down to the autoexec section (at the bottom of the file)
Copy the mount commands below the comments (indicated by a hash). The lines below apply to this example: [autoexec] # Lines in this section will be run at startup. # You can put your MOUNT lines here. mount c c:gamesdos c: # to start Prince of Persia automatically when installed: cd prince prince
Save the configuration file and restart DOSBox.
Play a game from CD with DOSBox
So you have found the original installation CD of a DOS game. But you can't install the game, because you need to do that in DOS! No worries! We have a guide which explains how to install and play a game from CD, all in DOSBox. Click here for more information!
Some DOS facts to keep in mind
In the DOS environment there are just 3 types of files that you can start/execute. These are .BAT, .COM and .EXE files. In this example (and in general when starting a DOS game), we'll look for files with .BAT (batch) and .EXE (executable) extensions. A batch file contains one or more lines of DOS commands and usually ends with the execution of a .EXE file. If you want to execute a .BAT or .EXE file in DOSBox, you can type in the file name without the extension. If there's a filename.bat and a filename.exe file in a folder, DOS will execute the filename.bat file first. If you don't want that, type in the entire filename including the extension.
DOSBox emulates the DOS environment, but doesn't support all DOS commands. It doesn't have to either. A list of supported DOS commands can be found on the DOSBox wiki section.
Supported games
With the method mentioned above, you can play a lot of classic DOS games. Here's an overview of some games, cherished by the DOSGamers crew, that you can play with DOSBox:
Wolfenstein 3D (fps)
Lemmings
Blackthorne
Sam & Max Hit The Road
Leisure Suit Larry
Lands of Lore: Throne of Chaos (rpg)
