John upgraded to Windows 10 on his desktop and his images are missing. Leo says this is a prime reason why you should always backup before doing an upgrade. John did, but he's still wondering what happened? Leo says it's been reported by several people and Leo says he hopes the photos were moved to another folder. It's possible that the images are in a 'Windows.old' folder or that the shared folder pointed to another folder that got deleted. Either way, it's bad behavior on the part of microsoft.
