Customize your Windows 7 login background
Windows hacker Rafael Rivera has found that Windows 7 has additional login backgrounds. This is an additional customization feature to be added by Microsoft which would allow users to have custom login backgrounds. It would be nice for organizations to have their company logo on the login screen or just home users to have a better design on their login screen. However, this feature would only be enabled in the newer builds or the Release Candidate of Windows 7. But Rafeal has got a trick to let you change your login background in Windows 7 beta.
