Windows was good for shareware developers because people had to buy utilities to like Irfanview to basically replace all the junk the OS shipped with. I eventually drop-kicked the whole OS and now life is good.
It's exactly the same for me. I've been using MacOS for 15 years, and just pressing the spacebar to see an image is a huge relief. I never had to install a simple image viewer on macOS. And if I did, xnView would also work, which I had installed on Windows before.
