You need to run all your
windows updates, until, until it says you are current
You need to visit a site and download the very latest Microsoft edge as well as POLICY DOCUMENTS
you need to extract files & copy a few to the correct folders
You need to use the Microsoft tool to make a special sites list enumerating the sites you need to operate in IE mode
You need to copy sites list to your
computer
You need to use policy editor to enable IE mode
Then run your firmware updates
It is a HUGE pain in the ass but IT WORKS
sadly, this is what Microsoft END OF LIFE PROCESS does for us
I will post my document in a couple hours & I will watch this thread
