Anyway, I've copied this from the Help text - would this do you at all (bearing in mind there should also be a security tag, which I
think you can use for restrictions as well):
To turn on Content Advisor and set limits
In Control Panel, open Internet Options.
On the Content tab, Under Content Advisor, click Enable.
If you've already turned on Content Advisor, click Settings, and then type the supervisor password.
Click a category in the list, and then move the slider to set the limits you want to use.
Repeat this process for each category you want to limit, and then click OK.
If a supervisor password has not already been set up for your computer, you are prompted to create one.
