You need to install Logon Studio first. It's a free logon changing program for XP and you can get it here: [link]
Then download the logon and unzip the file. Inside are 2 logons, a widescreen and standard res. Doubleclick on whatever one you need and it will open up the Logon Studio window and show in the list of available logons. Choose it and hit "apply" and that should be it.
If you have any problems, let me know. And yes, it seriously works.
Yeah, that looks good, but it's nothing worth spending my time on for a couple of buttons. Maybe when more things can be done with them I'll work on it, but I don't get any joy out of replacing a wall and a couple of buttons. I'd rather make wallpapers and XP logons for now.
