LogonStudio is a free program that allows users to change their Windows XP logon screens. It comes with several logon screens to choose from, along with thousands that are available online from Web sites, such as WinCustomize.com.

It also includes an editor for creating your own logon screen. You can build or modify logon screens by tweaking parameters on a list of elements. This allows you to customize everything from background to letterings to buttons.

Note: Windows XP Professional machines joined to an Active Directory domain cannot use LogonStudio since logon screens aren't applicable.
