First, basj had recommended my running your purge batch file, but my Bitdefender antivirus software blocks it, even when I suspend protection. So, I tried uninstalling and cleaning all references to Start11 out of the registry. Then, I reinstalled. The problem persists. I am willing to try the batch file again if I can figure out how to bypass my protection software and if I can verify that I am downloading that file from Stardock.
Second, the screenshot above is my Windows 11 Pro taskbar. I have a very wide screen and can show many more icons than I could on narrower screens. Not sure how to get this clarified.
Third, I have not intentionally installed explorer patcher or any similar program as far as I know. I do, however, run several utilities. Is there a search I can do to determine whether such a patcher or other taskbar utility is installed?
Thanks.
