I need to know if there is anyway to restrict users in windows vista home premium edition in the following areas? I want to restrict some users of the computer so they can access the internet, games, and word documents only. I do not want the user to be able to delete program files or change any settings to include backgrounds, screen savers, etc in other words restrict users to using the computer only without being able to make any changes. I would like to give them the ability to delete word documents only. Is this possible in this version of vista?

Thanks in advance for any help that anyone can give
