Once your user account is created, you are not stuck with the same name forever. Windows XP does allow you to change the name of your user account. For example, if your user account name has been JDoe for the past year, you can rename the account to JohnD without having to delete and recreate the account.
To rename a user account in Windows XP:
- Click the Start button.
- Click the Control Panel.
- Double click the User Accounts applet.
- Under the heading “Or pick an account to change,” click your user account name.
- Click the Change my name option.
- Type in a new account name and click the Change Name button.
