/r/sysadmin is full of Win10 horror stories for multi-user deployments in business environments. Your one anecdote just doesn't compare. I think Win10 is very undercooked, even by MS's standards. There are simply too many use cases where its a step down from Win7.
MS has more of less conceded that Win10 isn't business ready, so they have a special distribution called LTSB (Long Term Servicing Branch) of its Enterprise version. It doesn't auto-update, no feature updates, no cortana or edge, no support for app/modern apps, etc. Can you imagine windows 7 shipping with a lot of things stripped from it to make it more like XP? That would be crazy, but that's exactly what's going on here.
I think by 2017-2018 it'll be fine, but two or three years from release date to get something as stable as the previous versions seems really rough.
