I have Windows XP Pro. I have created profiles / logons on the PC so that I have my logon and the Children have theirs. When I install games and software on mine as administrator, they can access some and not others. Ie, I can play games and they cant, I can use some software and they can. How can I grant them access or bar them from some games and programmes?
Thanks,
Ian.

You can also go to start | Help and Support | type in search: policy settings

As XP Pro is meant as a business network OS you will notice that the policy settings can be quite complex. But perhaps the first link will be all that you need.
