How to use any image as logon screen background in Windows 7

Unlike earlier versions of Windows, in Windows7 you can change the logon screen background manually by altering the registry keys or automatically by using software. However the image size should not be more than 254Kb, or you need to resize it using another program. But with the new version of Tweaks.com Logon Changer, you don't need to worry about the 245KB limit imposed by Microsoft.

The Tweaks.com Logon Changer for Windows 7 is a freeware, portable tool that lets you customize the logon screen background with just a few clicks. It will give you the option to automatically resize and recompress the image to the highest quality possible. The original image is left untouched.

The application will prompt for the location of the new background image and then install the new screen behind the scenes. Tweaks.com Logon Changer will even provide a preview of your new background on a logon screen. When you have settled on a good logon background, click the Test button to see it in action.
