Windows has not had DOS in it since 95/98/ME, though CMD.EXE was not only built to emulate behavior of COMMAND.COM (and more) but also to provide limited compatibility with DOS software... DOS functionality has not been improved since XP, though it did somewhat better than Win2k with DOS programs. The real solution is to use DosBox, that way the applications wont malfunction (my experience is that tools which use less or no code depending on direct hardware access are most last and usually games and stuff like audio software are first to fail on CMD.EXE).

However if you have a program that already works fine on CMD then there is no reason to install DosBox for that... If you know that your going to need more DOS programs in future then it might be easiest to prepare and start using DosBox for those needs already.

Thanks for comment but the DOSBOX is not all, DOSBOX have little problem with dos resident applications like Print2File or Persian Printer Converters.
DOSBOX is a DOS Emulator for games and that's not fully supported of networking and printing and DOS office applications. In this situations you need to have a FreeDOS, DR. DOS or MS-DOS yet.
