Iwas shcked to discover that there's no programme with W10 that allows you to play DVDs. I've downloaded an app but every time I insert one, the default is that Windows goes to the store to find an app instead of playing. How do I change the default please?
Windows DVD Player is on my W10 machine and was not added or paid for by me. Just double checked on my Laptop and Windows DVD Player is there and working as well.
Anyhooo, to get back to OP question. When you put the DVD in to your machine you should have a box pop up (it pops up bottom right for me) asking what you want to do. Click on that box and you should see the options, including 'Open With....'
It seems the DVDs I was trying out were turkeys and I tried one I'd recorded and that worked - thanks for your help guys and gals, all your suggestions helped me to find my way round Windows 10.
