Louis is having issues with his start menu disappearing in Windows 10. Leo says that is one of the reasons why he recommends buying a Chromebook. It's just easier to use for basic computing. At this point, the best thing he can do is back up his data and start over. There's a recovery option in the control panel that will allow him to reinstall Windows. Then the problem should go away. It's a hassle, but it'll fix it.
