I noted VLC and the CNET Cheapskate BluRay player software at https://www.cnet.com/forums/discussions/cnet-cheapskate-delivers-free-dvd-and-bluray-player-apps/
"Read https://www.cnet.com/how-to/how-to-watch-dvds-for-free-in-windows-10/ for how you can get your FREE DVD and BLURAY player software.
We all know about VLC Player (or should) but what about BluRay? VLC Player can play unprotected BluRay but to date I've yet to encounter one of those.
This is especially great news for Windows 10 owners.
Remember my nod to ninite.com for VLC Player and why I give that nod."
Solution...download VLC media player and problem solved. Ever since my laptop has been updated with the Anniversary Update, my DVD player stopped working. I searched the interent to find a solution only to find none. There were so many suggestions of what to do, but none of the them worked. Then I read a suggestion and the person said he downloaded VLC media player app. So, I did and sure enough I can now play DVD's. It is great to have my laptop complete again...
