The difference is, Microsoft doesn't abandon their old stuff as soon as something newer and shinier comes along. I can still write a Win32 app today, almost 30 years after NT 3.1 came out. Even more impressive, if I use an old-enough version of the compiler and stick to a functional subset of the API, the program will run on both an NT 3.1 box and a brand-new Windows 11 machine.
