I have a Dell Inspiron 2200 laptop with Windows XP on it. I share my laptop with two other people and I am trying to find out how to restrict the ability to download things. Everytime I get on my computer, they have downloaded something and I want to restrict that because it is slowing my computer down. I have looked in the control panel and can't find anything but I have heard of people being able to block downloads. If you know how please help me figure it out.
