Greetings,
My name is Rhaine, I'm Independent Community Volunteer. I’m so glad assisting you today.
I am also using Windows 10. Let us work together to sort this out.
Windows 10 doesn't include the built-in ability to play Blu-ray discs, because Microsoft would have to pay a licensing fee to include that functionality.
You can go this link on how you can play the Blue Ray disc using you VLC application.
