I still need to learn the " cast to device" function? And I'm starting to hate how HP/Win10 is so damned automatic! Darn thing wants to send everything to one drive so it fills up the measly 5GBn they give you so you gotta buy more. That line starts @ $70/year! It isn't saving to computer's pictures, documents, etc. Just that damned one drive. Online sites won't go to one drive, just the empty computer folders. I need some data input on that stuff.
