Stardock LogonStudio allows Windows XP users to edit, change, and apply new logon screens. LogonStudio comes built with a visual editor to make it easy to create your own logons which can then be uploaded to websites to be used by others users. LogonStudio is free!
LogonStudio uses .logonxp files rather than requiring users to replace their actual logonui.exe.
