I subscribed to win10 auto-update for my win8.1 pro wmc. I am having lots of weird issues like network printer not being recognized everytime I use it and have to fiddle with it to get it to work. random lag issues. task bar vanishing on multi-monotor setup, etc. I read a while back someone saying you could install win10 from scratch after the upgrade and it would auto activate? If so, which version do I need to install for it to work. I don't want to have to install win8 then win10 and risk conflicts again.
