No worries, Peter. I really appreciate your (and everyone's) input. Computers can be elusive devils at times.
John, my big fear in doing a non-destructive reinstall on Windows 7 is the unknowns. For example, I have two image backups, but what if I forgot something? Then there's the driver issues. I must make certain they all work. The Windows updates scare the h*** out of me. I can see a lot of issues arising out of that.
I would hope an upgrade to Windows 10 would reset registry values so that my programs all work, including BIAB. Learning a new OS is less frightening to me than going through the hoops with a Windows 7 reinstall. At least with my two image files, I can revert to my original computer, albeit without BIAB working. But I need my computer for my profession as well. I work out of my home as a technical writer and technical writing instructor at Humber College Toronto.
Sounds like I've made up my mind
