My computer crashed. It was a HP with an upgraded Windows 10 Operating System. So, i could not save anything. It wouldn't even boot up anymore. I purchased a new computer. Another HP with Windows 10 Pro installed. When this new computer booted up, my old desktop background picture loaded as well. Then all of my old emails from the computer that crashed also loaded up. I'm new to computers. How is this possible? I did nothing and they were there. Can anyone tell me what's going on? Thank you, Tommy.
