Because people get used to what they used first. Since windows got a good lead in early 90's, network effects and inertia made it king on the desktop for so long. Had microsoft been able to release real smartphones with windows phone earlier, we'd be probably seeing a very different mobile world than what we see today. I quickly tried windows phone when they were released, they didn't seem worse or slower or less capable (except for fewer apps) than androids or iphones of the time.
