what about Settings/Apps/Default Apps - scroll to bottom and choose Choose default applications by file type
Find the ones that have Explorer now and choose chrome from the listing
.html for instance
another approach is still in the Default apps menu, choose Set Defaults by Apps
choose Google Chrome and pick manage
it should show the file types it can work with, and what is currently default. click the choices and change to Chrome.
why is it explorer and not Edge? ON my PC I have Firefox, Opera, Chrome and Edge as choices.
