Changing Account Usernames in Windows XP Home

Today I needed to change a user's username (not the displayed name) from "Owner" to first initial and last name concatenated (flastname). The normal WinXP Home control panel tools (at least the ones you can see) do not show this option, whereas XP Pro does. To change the account names, you must go to Start --> Run: control userpasswords2. Then from within this control panel, open the accout properties and change the "User name".

Just thought this might be helpful to someone else. God knows it's frustrating when Microsoft intentionally handicaps a product to charge less for it.
