When we say something in specified operating system, which preposition should I use? e.g.

I play games {in/on/under} Windows.

Programs run ON operating systems, but I think few people would say that they play a game on Windows, they would say they play a game on a computer running Windows.

I play games ON Windows.This is because any application runs on top of the Operating System.

If you say "I play games IN Windows", it could means games available as a part of the Operating System, present inside the OS. If you want to mean that, then I think you can say "IN Windows".


The answer might vary by country (Indian English, British English, American English). In the US, we would say "...games that run under Windows".
