I want to create a user group that can only click the start button and only open the games I have pinned to the start menu so that I can create a local account for my 3 year old and put him in it. I do not want to, will not, use a Microsoft account.

Actually, I want to download and import it but I don't even know if that's possible but it sure would save a lot of time

I know creating one is possible because I've been on those PC's at one job or another that are setup this way.

I know how to add a user group, I just can't figure out, or find a tutorial on, how to configure it.
