So I let my laptop update just a few mins ago to this instead of whatever it was before and I am having serious issues. Nothing is working right. IA looks weird and even Facebook. My school website said that it is not supported by this web browser, when it was the 7.0 or whatever it was.....

So...?????? is...what do I do? Will things update and pan out soon, or should I try to change back? And if so....HOW? lol
