The new version of Explore, in my opinon, sucks. I am generally a supporter of Microsoft products, but this is just too much. For starters, when you open Explorer now it automatically opens Bing, one of the most worthless search engines I have ever seen, in a separate tab. Maybe there is way to disable this "feature." If there is, I don't know about it.
Second, I have to try to open Explorer numerous times because it usually is just trying to connect but somehow can't do it. And, of course, it is trying to open both its homepage and Bing at the same time.
Maybe it is just me, I don't know. But this is infuriating and I am now using Mozilla Firefox.
