Freeware application LogonStudio brings full login screen customization to your Windows XP or Vista PC. Last week we showed Mac users how they can match their desktop & logon images, so if you were a Windows user looking for similar functionality, LogonStudio can do that for you and so much more. The app comes with several built-in login screens and images, but you can customize practically ever section of your login screen to your heart's content. LogonStudio is freeware, Windows only.
