Restricted User Access\Lockdown

[RenamonXP]

Ok I've got a computer here that has Windows XP Home on it. This is a multiple user computer the users range from a 7 year old to a 40 year old adult. There are 7 users to this computer and what was asked of me is if there is some third party software available to restrict access to certain things. What were looking to do is restrict access to folders and programs for some users I'm aware there is a way to do this on the machine already I just do not want to hastle disabling things and what not. I'd rather get a hold of some software that would aid me in this giving me a user friendly type of read out. I did this once when I took the Cisco classes but I never had to do it again after that. So yeh something that will not allow access to folders and certain programs.. Ill be here so hit me up with a responce!
