Windows 7 Logon Background Changer is a program that will allow you to customize the background of your Windows 7 logon screen. This way, you will be able to personalize the way your screen looks when logging in. You can choose any wallpaper to replace the default image that Windows shows.
The program does not have an installer. You only need to unzip the downloaded file in your system, and then double-click on the only .EXE file available. W7LBC will then display an interface with three buttons. Clicking on the "Choose a Folder" button, you can specify the folder that contains the image you want to use. Using thumbnails, you will be presented with all the images in that folder, and all you need to do is to click on your favorite thumbnail at the top of the screen. This will change the image on the logon screen. If you are satisfied with it, just press the "Apply" button, and your change will become effective from the next time you boot your system.
Finally, in the "Settings" section you will be able to reset the logon screen to the default, to prevent others from changing it, or to set the type of shadow effect you want for the text.
