If you’re sharing a Windows 10 device with your kids, letting them sign in with their own accounts will give them the freedom to explore safely while you’re still able to set up appropriate age restrictions and time limits, and make sure they’re not visiting any websites or using any apps or games that aren’t right for them. And even if your child has their own device, when they sign in with a Microsoft account that’s part of your family, the family settings you’ve set up for them will be applied to any Windows 10 PC, Windows 10 Mobile device, and Xbox One they sign in to with the same Microsoft account.
This tutorial will show you how to add or remove a child account from your Microsoft family online and in Windows 10.
