I want to change the user name to my computer. does anyone have useful information on how best i can do that?? thanks.

Go to control panel and hover to user accounts.

You'd be able to change it if you are the administrator.

I've tried that before. It didn't change the administrators user name.

Wich operating system re u using on d system , and for beta still go to start menu> control panel > administration > change user account or create new user account , den u re don after by inputing d user name and password
