[kubuntu] User "real" names don't match

view story

http://ubuntuforums.org – My "real" name displayed under Settings > Account Details seems to be different from what is set at Settings > User Management. Under User Management, I have my full name, but under Account Details it says my name is "Student". Long story, but this is how I'm guessing it happened... My old computer was a school computer with Windows, and the admin account was admin and my account was Student. After I left that school, the admin account was deleted and admin privileges were given to Student. Later, I installed Kubuntu through Wubi, which kept Student as my name. (Hardware)
