Surprising amount of drivers do transfer between versions of Windows, even if not officially supported. But yes, most break at some point.

I'm able to run binaries compiled over 20 years ago on the latest version of Windows most of the time. They do require enabling compatibility mode and sometimes installing legacy features.

I don't know, if APIs you mentioned are available in compatibility modes, but at least named pipes can still be enabled.

But Windows is going downhill lately, so backwards compatibility isn't what it used to be. Improving backwards compatibility for running old binaries would make Linux adoption easier. I hope that Linux PCs market share keeps improving to cross the threshold where it becomes an economically viable platform for most of commercial software.
