Most programs have some place where you can enter/edit user information. For example, in Word it would be Tools-Options-User Information.
So it's either finding out where these secret
little places are, or reinstall.
Regarding your folder options problem, you can always set one folder the way you like it and apply the settings to all other folders by means of Extras-Folder Options-View(maybe Display, im guessing these ones, since I'm running on a german OS).
Good luck.
