(In this post I use the word "game" to mean anything in the Steam store, even it's not a game per se.)
Earlier today I was curious what percentage of Steam games are not available on Windows, so I used a blank search to find the total number of Steam games (currently 85,828) and then narrowed by OS to find the number available on Windows (currently 85,807). So approximately 0.024% of Steam games are not available on Windows.
How can I find a list of these 21 rare games?

SteamDB supports this, somewhat. One of the parameters in its "instant search" is "Platforms."
If you do a search for Windows, and then add a
-before "Windows" in your address bar, you can run a search excluding titles supporting Windows.This by itself is not enough, since it seems there are some games that list no supported systems, and yet the Steam page shows it's available for Windows. If you narrow this down by adding one of the other platforms, you can get, for example, a list of games on Steam that are only available on macOS.
