If you're concerned about what your kids can see on Internet as well as how much time they spend browsing, you may be interested in how Vista expands parental control of their PC.
In Vista's parental controls, you can not only block inappropriate Websites, but also limit time spent playing games, using instant messaging software and browsing the Internet, as well as limit access to software applications such as Quicken. Plus, you can monitor how your kid's use the PC through via activity reports.
We recommend that you set up a user account for each child (older kids have different permissions from younger ones) and then administer each through a main account that is run by the parent using a difficult password with more than 8 characters and numbers to dissuade your child from discovering the administration account.
