After my desktop was upgraded yesterday at a time MS said looked convenient (it wasn't and couldn't be changed, ruining my plans for the evening), the problems are in two groups.
1) Things I could fix. I found that Epson Scan, the software that does the best job of controlling my Epson PSC, had been deleted. I thought maybe incompatible, but I re-installed from the .exe file I downloaded 2 or 3 years ago and it works again, no problem. Strange and unacceptable to delete my programs without a word.
2) Unfixable to date. The most irritating of these is that File Explorer details view (or any other) no longer shows the file information panel when you click (select) one, or several, files. I use this continually to view or add tags, comments, date taken etc to one or more images (for example). It's a brilliant facility, easily add a tag or comment to multiple files. A work round is to display properties, and work your way round to the relevant fields, but this is very much less convenient and takes much more time. It will seriously impact my ability to complete tasks on time. I can't find anyone else reporting this, but it's unlikely to be just my PC affected.
UPDATE: I found the correct solution to the File Explorer issue. In the ribbon on the 'file' tab there is an option to turn on the details pane again. Why MS turned it off by default and didn't respect previous settings, who know.
