I gotta run, Mr. Delbridge, but it you decide to manually update Windows 10 to 1607 with the anniversary update, make sure you have a full system backup.

I'll be in your neck of the woods (Carson City) tomorrow afternoon. I'll be happy to stop by if you think you could use some help.

Will do, for sure.  I just purchased Acronis, after realizing that Windows' built-in image backups are restricted to 25% of available drive space.  Thought I had six weeks of rolling backups on my dedicated backup drive but turns out I only have one.  D'oh.
 
That's very kind of you re visiting!  I was supposed to be in Carson tomorrow too but had to cancel on account of this *&%$ cold I picked up in DC last week.  Otherwise, I'd invite you to drop by for some BBQ.  Some other time?

Resort, can you add SOLVED to the title of this so other users can see the problem was fixed?
 
Thanks

Done.
 
I was still hoping for some replies re Windows 10 Device Manager, but I suppose it's water under the bridge by now.
 
Thank you, everyone, for your recommendations and kind assistance.
