I updated to Windows 10 from W7 a few weeks ago and was very pleased with Edge, it loads pages quite fast; some may say because it does not support extensions, but I was very surprised that it didn't. I'm certainly looking forward to the day it does as it could be the browser of my choice then, but without things like Adblocking and Script blocking, not to mention the extensions that tell you whether sites are safe or not when Googling, it doesn't feel that safe or secure which is why Firefox is my choice at present, although IE, Chrome and Opera are occasionally used.
