Windows 7: User Name Changed but Log In Remains

I'm using a Win 7 Home Prem SP1 x64 system.

My Problem:
I have changed my User Account Name, However I must still log in using my old User Account Name

What I've done (more or less in-order):
-Secure Logon - Press CTRL + ALT + DELETE to log on
-Log On with User Name and Password
-Lock Computer Screen - Display User Information or Not ("Do not display user information")
-Display Information About Previous Logons During User Logon in Vista and Windows 7 ("Display Logon Information")
-Changed User name



I realize that it may work if I undo the four changes but I don't want to undo and redo all of these steps. There must be an easier way.

You should have created a new user account.

In all other circumstances when you change your name, your login name changes as well.
