We were lucky enough to come across this issue when one day, almost all our internal functional tests (we use our in-house EasyTest engine) for XAF Web UI failed due to the following error:

    Type:       UnauthorizedAccessException
    Message:    Access is denied.

    Data:       0 entries

After several hours of researching and googling, we found out the Installation of KB3025390 breaks out-of-process JavaScript execution in IE11 ticket on MS Connect
as well as possible workarounds at https://code.google.com/p/selenium/issues/detail?id=8302


Just wanted to make sure you will not waste your time on this as we did and also, because we started receiving reports from our customers on this.
