Smart TV acquiring videos, photos from computer

[DAVID L STAHL]

I had windows 8.1, I could go to Media App on my Smart TV, hook up with my computer and find videos, etc.... After installing 10, Media goes to computer just as before and goes to: david@nwt\video\root. I cannot find this location on my computer and cannot change the location on the TV. Any ideas? Thanks for any help you can give. David
