A published IE application may show the following pop-up when starting a web page:
Such pop-up appears each time, even if you click on the ‘Don’t show this message again’.

The value is “NoProtectedModeBanner”, DWORD, and must be set to 1.
It must be located under HKCU\Software\Microsoft\Internet Explorer\Main
