Windows over Linux based OSes. The support (albeit via mass adoption) is much better. I can run almost any old software, including games. Plug in anything that's plug and play and not worry about driver compatibility. Things tend to just work and I'm not one accidental sudo away from wrecking the whole OS.
I just disable ads, put a custom start menu in place, and I'm golden.
I'm not saying Windows doesn't have issues, but for me personally it's likely far less than a Linux OS.
