I've got dozens of Windows 10 computers at my disposal on separate networks installed using separate media... Every installation of Windows including fresh installations with latest patches all have an IEXPLORE.EXE process and sub-process running under DCOMLAUNCH process and occasionally I see them connecting to Microsoft's servers....
If IE has been "officially retired" why does the operating system still launch the browser? What is this process doing? Why is it making connections to MS servers?

These IPv4 ranges are owned by Microsoft:

And yes my default web browser is Chrome, but I'm sure that anybody looking into this will see the exact same behavior on their machine as I do.. Running Windows 10 x86_64 with latest updates:

Any insight on why this process is running? How can MS claim browser is "Retired" when core OS features still depend on it? If anyone can figure out what core features these are, maybe we can disable them... Hopeful for any insight. thank you
