THANK YOU! The Windows 11 registry fix appears to have done the trick for me. After two calls to the I.T. help desk, it was apparent that they had no interest in helping me fix this problem. I have suffered with perpetual pop-ups for the last four days. I’m going to share this solution with the help desk; maybe it can save someone else from this aggravation.
