I just set up Family Accounts in Windows 10, and we've had the PC for about 2 months already. I set one up for my son, but I'm mostly concerned he's spending too much time on the computer and want to set time limits. Once he had his own account, though, it seems that he's lost access to all games. Steam, settings, levels, skins, etc.

How do we restore those things and allow him permissions under the Win 10 Parental controls and family?
