Sandra has family that is relying her to be their PC support, but it's hard because she's in another state. Leo says that's the benefit of using remote access. But the danger is, that once they know she can do that, she won't have a moment's peace. Since Sandra's family is older, she could send them to The Elder Geek, where they can learn about computers. There's also How To Geek. Que has a great book series called The Absolute Beginner's Guides.
Leo also recommends that Sandra encourage them to get a Chromebook. It has a power wash feature that puts the computer back to factory settings.
