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:    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
