Windows 10: How do you want to open this file? - Every time

And if you have a link to a file type other than jpg?

And what do you have here?

 

Looks the same:

UPDATE- This problem is not limited to Excel, so it's possibly back to Windows 10 as the problem
I received some emails containing image files, and clicking on any of them normally would open the file with the Windows default program, but like Excel, I keep getting the "how do you want to open this file?" every time.

 

I get a feeling of déj vu when I see this thread:

keeps popping up despite default! - Windows 10 Forums

perhaps there are insights there?

 

Thanks, I did look there when you suggested it earlier. The only thing I haven't tried is to create a new user/profile.
