I feel sympathetic to Windows OS developers because the code must be a huge bloat to keep up with decades of backward compatibility and have to go through codes that many generations of people had written to even change a thing which made it pretty much stuck on its own weight. But I can probably still be fine what OS I am on as long as it has quality third party apps but interestingly as a web dev, it's all on macOS and have no intention of moving away as it'll kill my smooth workflow. Tried to check if I could use Windows for it a few years ago but figured it's a pain in a few hours. I can see MS is trying though, when they start including Linux in Windows. And I like their tooling very much, like VS Code and TypeScript but I don't see myself switching away at least for the next 5 years.
