In a new Building Windows 8 blog post, Microsoft has today revealed that is has plans to make Windows 8 safer than ever before with new family safety features. One of those features include new "children" specific accounts, which allow you to set time limits and restrictions easily.
The new child accounts allow parents to have full control over what their children are doing on the internet. For example, parents can set time limits and turn on web filtering for their kids, which would restrict them to a certain amount of time and block them from censored websites.
Not only that, but you can also receive a Family Safety report, which lists the child account's downloaded apps, visited websites, most used apps and more. "With Windows 8, you can monitor what your kids are doing, no matter where they use their PC. All you have to do is create a Windows user account for each child, check the box to turn on Family Safety, and then review weekly reports that describe your children’s PC use."
This does not require any specific downloads, it is all inclusive with Windows 8.
The new children accounts are a great way to make sure your kids are safe online, I personally like the time limit feature that will automatically log off the account after the amount of time set is up.
