The issue seems to have resolved itself, or there was a problem with Visual Studio 2015 Enterprise I had on my system. The trial license I had was close to expiration, so I uninstalled VS and installed VS 2015 Community. While at it, I accidentally mis-clicked something in my task bar and the upgrade to Windows 10 window opened and I thought I'd give it another shot. I hadn't tried the upgrade for several months, but there were no significant changes on my system, except this uninstall and regular updates.
The next day I had Windows 10, and now I have another set of problems, but I'll ask that elsewhere.
