Manage programs, games, and time limits

After you've turned on Parental Controls for your child's standard user account, you can adjust any of the following individual settings that you want to control:
Time limits:

You can set time limits to control when children are allowed to log on to the computer. Time limits prevent children from logging on during the specified hours. You can set different logon hours for every day of the week. If they're logged on when their allotted time ends, they'll be automatically logged off. For more information, see Control when children can use the computer.
Games: You can control access to games, choose an age-rating level, choose the types of content you want to block, and decide whether you want to allow or block unrated or specific games. For more information, see Choose which games children can play.
Allow or block specific programs: You can prevent children from running programs that you don't want them to run. For more information, see Prevent children from using specific programs.
