Kinda depends where you work.

I’ve been working full time in software dev and hardware dev since the mid-1990s. Through that whole time I’ve worked almost exclusively on (in the early days) Sun workstations, AS/400, and HPUX machines. This eventually transitioned to Linux and macOS (once it became Unix based). Over the past 7-8 years, every company I’ve worked for (primarily in backend software and “big data”) has actually heavily restricted Windows within the company. Most have required high level approval to have a Windows machine… you had to have a damn good business reason to run Windows as your primary OS.

Windows is definitely the leader in generic desktop work, but… there are pockets out there of Linux/macOS-only. And… given the strong shift to browser based everything… Windows has lost its shininess for all but the most specific applications - eg graphics editing in industry standard tooling like Photoshop.

Thankfully the school my kids go to doesn’t really give a crap what you run at home on on their laptops they used for school work as long as the kids are able to to their assignments. Almost 100% of what they do is browser based interfaces anyway, so it doesn’t matter what the underlying OS is. I’ve made a point of teaching my kids Linux, macOS, and Windows. They’ve both asked to run Linux on their personal PCs… it was, and remains their choice.
