This question is in continuation to the one asked in github selenium support.
https://github.com/SeleniumHQ/selenium/issues/6098
Now we have trouble identifying the IE Authentication window in selenium. Alternative is to use the https://<username>:<password>@<rest_of_url>.
Since IE is blocking this approach due to the security reasons, we tried to make the necessary registry changes as mentioned in the following link.

Even these change are not helping us as the IE keeps on popping up the Auth window. Kindly let us know any workarounds as this has a significant effect on our software releases.
