Yet another plus for being a consultant is running into issues never seen before, searching for a solution, seeing tens of thousands of hits with no solution in sight, and coming up with a solution. I have done many XenApp 7.x and XenDesktop 7.x deployments where Internet Exploder, I mean Explorer, 10, and 11, were used, and I have never seen or heard of this issue. On a recent project, I was asked to finish a XenApp 7.6 deployment running Windows Server 2012 and Server 2012 R2. One of the issues I was tasked to resolve was that IE 10 and 11 had two weird issues for any user, regular or administrator. This is how we solved the issue.
