How to Rename the Built-in Elevated "Administrator" Account in Windows 7 and Windows 8
Information
This will show you how to rename the built-in "Administrator" account name to any name you would like instead to be displayed on the Welcome screen, log on screen, Start menu, and C:\Users\Administrator folder in Windows 7and Windows 8.
You could have better security by not using the same default name of Administrator as everyone else does.
Note
The built-in elevated "Administrator" account is not enabled by default in Windows 7. Instead you use a default normal administrator account that was created during installation. This normal administrator account is not the same as the
built-in Administrator account.
Tip
When you change a name of a user account, the original name is still tied to that account even though the new name is displayed in the Start menu and at log on. So you will not be able to use both names to rename another account with without deleting the other account that already has the name.
EXAMPLE: Built-in Elevated "Administrator" Account at Log on
NOTE: Top screenshot is the default name, and bottom screenshot is renamed.
