One thing that I do not really like about Windows 7 is the default logon screen. The wallpaper that is being provided is a little childish and light in color. However, there are no customization tools by default in Windows 7 to allow you to change the logon screen. Fortunately, there is a tool out there by tweak.com which allows you to change that default Windows 7 logon wallpaper easily. You can download it here
To use the logon screen tool, just simply run the extracted .exe file and click on the “Change Logon Screen” button to select a background which you want to use. In case you need to revert the background back to it’s original image, just run the same program and click on “Revert to Default Logon Screen”. Pretty simple eh?
