BLOG by Dennis Garavsky: Beware of Windows update KB3025390 as it breaks EasyTest functionality in Internet Explorer 11

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:Accessisdenied.

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.
