Hi Ryan, my name is ***** ***** welcome to JustAnswer!
I'm not sure who told you that you can play XBox One discs on your PC but you were misinformed. XBox discs are manufactured in a way that they are only readable by that particular machine and cannot be read by a standard computer DVD player. It's kind of like how PlayStation games can ONLY be read by the PlayStation and can't be read by a PC or any other system. The XBox is the same way.
With that said, Microsoft HAS made it possible to play XBox ones games on Windows 10 via streaming from your existing library. For full information and instructions on how to do this, please see the following link:
I wish there was a way to just pop those discs in and start gaming but unfortunately it doesn't work that way. Let me know if you have any other questions on this.
