Well, after 2 hours on chats and the phone, and having to reinstall Word (plus the agent re-reinstalling again), I got Word back. (Why is it that tech agents just don't listen? They are trained to follow their steps in order, and they just don't care that you've just done those same steps.)

So, my apps are back. Yay!

Hyperlinks to jpgs still don't work. BOO!

One thing I did learn was the only changes to my system were Win10Pro updates on 5/1 and 5/8. Suspicious. Awfully suspicious.
