For my broadcastify feed, it's running windows 10 pro, absolutely no issues other than a hardware failure with a faulty ram stick a few months back - which is completely unrelated to windows 10 itself. The machine has been running 24/7 since Jan 2016 (barring a few windows updates here and there (defer updates are really nice)).
Overall, I'm quite pleased with windows 10. Plop Win10 on a SSD, and the machine boots up in seconds, it's very fast. Below are my Broadcastify machines stats to give you an idea.

I thought about getting a volume licence copy with Windows 10 Enterprise with all of the windows 10 machines in this house honestly. Never went through with that however.
