PSMail Quick Tip: Though it may be convenient to give all users on your home computer the same privileges, for security purposes it’s best to create not more than two administrative users, especially in this age when home users have in-house networks. Give younger children and teenagers basic user level access only. Both Macintosh and Windows PC allow you to create non-administrative users for basic computer functions like playing games, word processing, and surfing the web. Restricting the use of administrative users on your PC helps keep your family and your information safe.
