You can't for example run apps that use CGA, EGA or VGA graphics mode, only text mode, and don't expect internal PC speaker or its emulation to work, that support was dropped long ago. While it is true that 32bit Windows still supports some MS-DOS apps even in modern versions (Windows 10, Windows 11), the DOS environment emulation is drastically limited. I am sorry but you can't have your cake and eat it. But you should understand that this comfort has been achieved with technological advances to which the old DOS apps do not adhere. Oh, I perfectly understand what you want: You want to mix the comfort of the modern operating environment and the old DOS app. So, in case of 64-bit versions of Windows, the support was never dropped because it was never added in the first place.Ĭan some sort of compatibility mode be installed in newer versions of Windows operating systems? The reason is the x86 architecture of Intel and AMD which does not support 16-bit operations in long mode. Only 32-bit editions of Windows support DOS apps which are 16-bit. Why has the support been dropped? Was it for technical reasons or marketing reasons? The catch is that a DOS program does not only expect DOS, but also a DOS-era computer, like a 40 MB partition, FAT16 file system, etc. "What's the catch?" you are probably asking. Get ready to be surprised: The last version, as of this writing, is Windows 10 32-bit version 1703. What is the latest version of the Windows operating system that can run DOS applications without using DOSBox which in my opinion is a pain to use?
