When you install Windows XP, you are asked during the installation process to put in your full name. Later on, the installation process will ask you for the user names for the various accounts. Of course, you can have names that are different in both instances. For example, let's say I put in the name John Smith (me) as the owner of this copy of XP, but when it is time to create the first user account, I put in Mary (because she is the only user on this computer). Later on, I can easily change Mary name to something else as needed. However, I have not found a way to change the John Smith name. This name is shown when you right click on My Computer and under the General tab, you see the phrase: "Registered to". How can I change this name to something else? This would come in handy when I sell my PC and does not want the buyer to see my name on his "new" PC.
