Christopher, thanks so much for taking the time to help me. I really appreciate it!
While not wholly clueless when it comes to tech, I have to admit that I'm not familiar with winget upgrades.
Would running winget allow me to pick and choose the upgrades I want to install? Or does it automatically upgrade any and everything eligible for an upgrade whether I like it or not?
If possible, I'd prefer to avoid a full-scale, soup-to-nuts Win 10 upgrade, with all the havoc that major upgrades sometimes cause. I've been burned in the past.
Thanks very much for the Visual C++ download links you posted for me. If I chicken out on winget, I'll download and install the two files manually.
All the best to you!
