Got Win-10 Tech Preview Build 9860 back again!

It's been that kind of day. I started it with Build 9860, messed up, had to install Build 9841 from DVD to recover, spent most of the day replacing programs, icons, gadgets, etc., and then at suppertime, with everything working again, got into PC Settings > Update and Recovery > Preview Builds > Download Now and downloaded then installed Build 9860 again. And now I'm back where I began, just a little older and wiser. The moral here? "If it ain't broke, don't fix it!"
