Also essential in our day and age, this provides a whitelist for specific user logins.
You can download it at
Windows Live Essentials and then activate it in the Control
Panel (activate Parental Controls). It provides time limits (for specific user logins),
the ability to block games / specific programs, and either an internet whitelist
(which allows only specific sites you designate) or a blacklist (which disallows
bad sites according to Microsoft's blacklist).
Cons: It doesn't work on Administrator logins, only "standard" user accounts.
In addition, I have seen that sometimes it just stops working for no apparent
reason... perhaps Microsoft's servers get overwhelmed? Use this in combination
with the other tools listed. (Note: to remove the chat program 'Messenger',
just uninstall Windows Essentials, and it will prompt you for which programs
specifically desired for removal--so you can leave Family Safety).
