Many times I and many others like to make their pc environment personal. This includes changing the background, the themes, the folder icons, layout of icons, organization of content. The problem is that it typically hidden or removed and so workarounds are required.
Login Screen Background
- I and many others change their login wallpapers. This does not exist in Windows 7 at all. The current alternative is LoginStudio which is designed to work with Vista (lacking the capability to change that wallpaper). Or alternatively to that, it is a dll called imageres.dll in the Windows folder.
Modify the personalize screen to have this ability to change the login screen wallpaper. You can reuse the change your desktop wallpaper and provide a preview into the login screen.
