I did not update my W510 but did the desktop computer to 8.1 pro preview. The only complaint I have so far is with IE11. I have problems with two secured web sites (HTTPS
. One an employee web site of a major airline the other is Discover Card web site.
I doubt if many could test the airline site but hopefully some can check the Discover Card site.
On the Discover Card site, under recent activity, there is a “+” in the description area to click on that gives you more information on that item. With IE11 on my desktop nothing happens when I click on this “+”, it works okay with Google Chrome on Windows 8.1 and with IE10 on Windows 8.
