I think it is rather more a case that those who are having issues short louder and more frequently than those who don't. I don't use edge as I just don't like it. Win 10 is as fast if not faster than 8.1, I use Firefox and it is just as quick. I'm curious to the spec of machines of those finding it slow. Apart from having one game not work, until I found I could redeem my retail version for a steam version and it works out has been fine. Definitely prefer the interface over the metro style that works great for tablets and phones not for pc.
