This is being repeated continuously but in reality this isn't the case in practice: Half if not more of the videogames I owned in the 90s stopped working on Windows XP, and some of those which kept working also failed under Vista/Win7. If you sent a modern PC to the media from 1990, they would indeed notice that their favorite game cannot run on it, despite the general compatibility effort from Microsoft.
