The experience of using Windows 10 is that you walk away from the computer to watch something on TV and when you come back the OS has quit out of all your work applications so it can reboot the computer so it can stuff advertisements (in this case "weather"; apparently news and stock quotes are a kind of weather) into a new place on your computer (in this case the lock screen; I already had one type of advertisements disabled on the lock screen, so they added a second type)
