Windows has some pretty amazing backwards compatibility. In many cases, you can run ancient 32-bit Win32 applications just fine on your current system.
However, there’s one issue: If you ever tried to run a 16-bit application from the Windows 3.x days, any 64-bit Windows version (starting from Windows XP) will refuse to run the application with an error message indicating that you should ask the vendor for a compatible version.
On the other hand, the modern 32-bit versions of Windows run these applications just fine.
Thanks to two amazing open-source projects, you can bring back 16-bit compatibility to the 64-bit Windows era.
This one’s from 2022, but apparently, I never mentioned it here on OSNews.
