Andavari's response is really helpful. I am very familiar with the registry, but the key referred to in the published instructions is not there. I was unsure if this was a change made by Microsoft (a familiar problem) or if I was supposed to create the key. It takes hours to make a disk image to make sure things work properly with the new reg. I know I could back up the reg and usually Win 10 will load "last good" but that is a gamble! So thanks for the clarification. Now if Edge would just get its act together with Flash player I would use it!
