Doesn't everybody have access to the extended Win 10 support at no cost? When I went to Settings>Update & Security> Windows Update there was a box that I clicked on to start the process. (I don't remember the specifics; I did it a couple of weeks ago.) Then while poking around the web I found a website that gave instructions on how to add that box if it didn't appear. My son used that information to successfully get the extended support on his PC.
