Does anyone work in an “enterprise” environment who have been dreading this day? Any apps / mainframes / industrials systems that needs IE to run?
There is also "Internet Explorer Mode" in Edge, which uses iexplore.exe under the hood.
Additionally, if somebody were _really_ desperate to launch iexplore.exe itself, then there are unsupported means to do so.
For example, via manually modifying the registry key "NotifyDisableIEOptions" under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Main\
My favourite hack though, which should not be used by anyone ever, is launching via the COM object interface, which bypasses the registry key check [2]. I have personally verified that this works(!)
