Application support; some popular software is built with Windows in mind.
One-click installers; Software usually comes with user-friendly installation wizards. No command lines or dependency juggling. Also better compatibility woth past versions
Driver availability; Linux is getting better, but Windows is superior
Better peripheral support like for printers, webcams, game controllers.
Gaming performance; although Linux is gaining ground, Windows is just better in this regard
Media codecs and formats; again, Linux is getting better, but this isn't always an out-of-the-box experience
Business integration; Windows plays nicely with enterprise tools like Active Directory, Microsoft 365, and legacy business apps.
Don't get me wrong. I use Linux as my daily driver. That also means I get frustrated on occasion when again I must consult man pages instead of just running a troubleshooter or fiddling with Nvidia drivers instead of just running the game.
Personally I find that linking "making money" with "climbing the social ladder" is at the core of many of our issues.
Going even further, ranking each other based on factors like wealth, education, occupation, influence, etc. is degrading and leads to inequality, corruption and emotional/mental health problems, to name a few. The idea that success is measured almost exclusively by economic gain and social rank distorts human values.
Sometimes I wish media organisations would report with the same hunger about every tiny, little unimportant feature in software I'm involved with.
Then again, it isn't millions of people using my stuff.
