Well, I have these computers that came with XP Home preinstalled and with the logon username of "Owner." Well I wanted to change Owner to something else - lets say "Jim" so I went into Control Panel -> User Accounts and changed Owner to Jim. On startup the default username in the box is still Owner! I found a registry setting called "DefaultUserName" and changed it. It works for one reboot then changes back to Owner. Any ideas? Microsoft's support pages recommend making a batch file that changes the registry setting to whatever you want as a default then setting it up to run at every startup. That seems pretty lame to me. Thanks.
