Kids Corner control function win8 new member?

In the Windows 8.1 Build 9369 leaked a few days ago, some netizens discovered a new feature ——“Kids Corner", users familiar with Windows Phone 8 should be familiar with this.

Kids Corner
This user found an "Kids Corner" icon in the imageres.dll file of Windows 8.1 Build 9369, which is a function that helps parents manage their children's use of the computer. The function first appeared on the mobile phone system WP8, which is quite practical.
With this feature, parents can set their child's access to the computer, such as which applications and duration of use, so that children can be better controlled to prevent them from overusing the computer or being harmed by inappropriate online content.
However, it is strange that there is an account management function in Win8 that can achieve this effect. The reason for increasing "Kids Corner" may only enhance some effects.
At present, this feature is not enabled, but there is such an icon, so it is still unknown whether it will actually go online.
