LogonStudio 1.7

LogonStudio is a new program that enables users to change their operation system logon screens. Users can apply logon screens that come with the program, create their own, or download hundreds of additional logon screens created by others. 

Besides, LogonStudio enables you to build or modify logon screens by tweaking parameters on a lengthy list of elements. So you might, for instance, change the FirstColor parameter of the Centre Panel element to a new shade of blue. This allows you to customize everything from background to letterings to buttons, but beginners will find the process quite confusing. The sketchy online help isn't much assistance, either.
