The fact that a compat mode exists means that Microsoft put effort into backwards compatibility. Windows even emulates some old bugs for old popular apps that depended on them. I don’t think any other OS does that.
I don’t like Microsoft Windows at all, but you are absolutely right about doing a good job with backwards compatibility.
Linux isn’t so backwards compatible, but with much of it having open source code, you can often compile it again yourself—tho having been written in a language that offers good backwards compatibility also helps.
Tell that to video games, which constantly need a compat mode enabled
