Have WIN10 on a laptop, came installed, and it's a chore to go through and turn off all the useless jumping unicorn and spying stuff that's installed. Spent serious time unchecking all the default privacy settings, and installing Norton, Spybot, CCleaner, Office, etc. but it mostly works. There is a way to get around the defaults and install IE for browser if you want that. WIN 8 was a disaster. My workstation purrs along on WIN7 and it be it's a much more stable, less bells and whistles, spying type of platform. I may bite the bullet and install 10, but not in the near future.
