Thanks, Larry. And thanks to you, Notes, for the addtional information. I'm one who is extra careful with externals,
having been warned they are sometimes used to carry malware.
Consequently, I plug in to USB, use it, and eject. Sometimes I don't, and walk away. That's when I am wondering if MS's rather intrusive auto updates could present a problem? Sometimes I'll look over at the PC and the download has already happened

It raises the question, what about the BiaB on the external?
