NTVDMx64 is an unofficial patch of Microsoft's NTVDM (''NTVDMx64'NT''' '''V'''irtual '''D'''OS '''M'''achine) for 64is a port of the Windows <abbr title="NT Virtual DOS Machine">NTVDM</abbr> from non-bit Windows. Created x86 machines to x86_64 developed by a person who calls himself Leecher1337, it . It allows 16-bit DOS Windows applications and games to run work on 64-bit Windows. It is partially based on the leaked Windows NT 4 source code. Recent versions of NTVDMx64 allow running 16-bit Windows applications and games on 64-bit Windows<ref>http://www.columbia.edu/~em36/ntvdmx64.html</ref>.

NTVDMx64 can run text-mode DOS applications as well as games such as Doom, but since NTVDMx64 is very slow and uses non-standard ways to run 16-bit applications and games, it is recommended to use emulators such as [[DOSBox]], [[vDOS]] and [[PCem]], virtualization software such as [[VirtualBox]], [[VMware Workstation Player]] and [[QEMU]] etc. to run 16-bit applications and games on 64-bit Windows.  It was tested on the following <b>x64</b> 64-bit versions of Microsoft Windows:

NTVDMx64 was initially incompatible with It is based on the NTVDM implementation in the MIPS, PowerPC, and Alpha ports of Windows 11 x64, due NT 4 which used "SoftPC" processor emulation to provide x86 software compatibility. By porting the emulated CPU from the fact that leaked NT 4 source code to x86_64, 16-bit applications could work on 64-bit systems. ==Review==NTVDMx64 was initially unable to run when Secure Boot is enabledvery slow, which is required for Windows 11 x64 and it uses non-standard ways to install run 16-bit applications and run. The authorgames, Leecher1337 added loader support for Windows 11 x64 to NTVDMx64. This also applied to Windows 10 x64, when Secure Boot is enabledso alternatives are recommended where possible.
