As the Windows 95 project started to come together, I was approached to undertake a special project: Run Windows 3.1 in an MS-DOS virtual machine inside Windows 95. This was the ultimate in backward compatibility, along multiple axes. First of all, it was a demonstration of Windows 95's backward compatibility by showing that it could even use an emulated MS-DOS virtual machine to run the operating system it was designed to replace. Second, it was the ultimate backward compatibility.

If you had a program that simply wouldn't work with Windows 95 for whatever reason, you could fire up a copy of Windows 3.1 in a virtual machine and run the program there. To use it, you installed Windows 3.1 and Windows 95 into separate directories, and then made a few edits to the Windows 3.1 SYSTEM.INI file to replace the mouse and serial drivers with special versions. There were some other preparatory steps that had to be done, but eventually you got to the point where you could double-click the Windows 3.1 icon, and up came Windows 3.1 in an MS-DOS virtual machine. Although you could in theory run Windows 3.1 in a window, the experience was pretty bad in practice for a variety of reasons. Computer systems of that era simply didn't have the computing horsepower to render the video fast enough. And you wanted keyboard hotkeys like Alt+ Tab to switch among your Windows 3.1 windows, rather than treating Windows 3.1 as one giant program to be switched into or out of. Running Windows 3.1 as a program inside Windows 95 served as a convincing technology demonstration, but the feature was cut shortly after it came together.

One reason is that. There was no integration between Windows 3.1 and Windows 95. If you copied something to the Windows 3.1 clipboard and then switched back to Windows 95, then tried to paste from the clipboard, you didn't get what you copied from Windows 3.1, because Windows 3.1 and Windows 95 had separate clipboards. Similarly, if you had a Word document with a live link to an Excel spreadsheet, and you opened the Word document in Windows 3.1 but the Excel spreadsheet in Windows 95, not only did the live link not work, but the copy of Word running in Windows 3.1 would get a file sharing violation when it tried to access the Excel spreadsheet, resulting in confusing error messages. Because even though they ran in separate virtual machines, they shared a file system.

But perhaps the biggest reason for the feature to be cut was that its presence would undermine the compatibility story of Windows 95. Windows 95 was intended to be maximally backward compatible with all your Windows 3.1 programs. The compatibility would be so great you would never turn back. If there were this 'Run Windows 3.1 in an MS-DOS virtual machine' feature, it would be an admission that we failed: We gave you a way to turn back. Somebody managed to dig up this unfinished feature from a leaked build, so. (The feature didn't make it very far past the phase, so don't expect to be impressed by the user experience.).

In a someone related vein, there is a guy who is writing an emulator that lets you run 16-bit Windows applications on modern Windows. You rename your 16-bit application to MyApp.exe16, and his application is registered to handle the the extension. He virtually loads the 16-bit image, and maps all the imports to stub functions that turn around and call the real WinApi functions: – MessageBox – CreateWindow – etc The program, written in C#, is a 16-bit processor emulator. When it needs to call various API functions, they are translated to the full (64-bit) version by his Windows-on-Windows layer.

[Why I’m writing a Windows 3 Emulator]() •. I honestly don’t think you need to even do that, if you wrote something that redirected the calls to a translation DLL that mapped the 32bit handle to a fake HANDLE for 16bit you’d probably be (mostly) fine. IIRC 16bit code will run fine in 32bit mode the main issue is just the OS primitives you’d have to translate for. That said there are probably also about a million backwards compatibility bugs you’d have to emulate too like people using LoadLibrary and GetProcAddress to get undocumented functions. But in theory.

It could work. For my important 16-bit apps (OK, games) that finally stopped working acceptably on Windows 10, I’m just using a VM running XP – I’d previously tried one running Win98 (low resources!), but that was a hassle due to things like Win98 not understanding NTFS, for example. XP seems to be a good compromise between “modern enough to be useful” and “old enough so that my old games run properly”. (And I had an XP CD lying around.) I have disabled the network adapter on the VM so it can’t see any network, though. I did have to use XP Mode for a while at work when we upgraded to Win 7. Eventually the software we had to use it for was updated, piece by piece, and then we didn’t have to use it any more.
