The latest update Dec 2 2015 seems to have caused havoc on my system At first i was pleased because browsing through edge worked wonderfully. unfortunatly, it complete killed the ability to work with any tile based programs such as the news feed, passwords packlock, and even the app for Google Chrome. They are completely 100% unusable as all it does is go through driver crash after driver crash. My book WAS working very well. The Dec 2/2015 just screwed it up hardcore.
