5 year old uninstalled almost all my games

And if you have an Xbox Live subscription your saved games should sync right back when you start the game

They should all be on ready to install so you can install them again.

And so my friend youll be spending a while on reinstalling then.

Oh dear. You should be able to download them again.

Hi there! There’s a few pages I think you should check out to help prevent issues from arising around your little one using your Xbox. Firstly, check out this link for information on the benefits of, and how to setup family controls and parental restrictions
on your Xbox/your child’s profile:

https://support.xbox.com/browse/xbox-one/security/Family settings

Secondly, this link will give you more information on how to install the digital games you own, under the “Reinstalling Games” header part way down the page :

https://support.xbox.com/games/game-setup/install-games

Hope this helps, cheers!
