Unlike previous versions of windows,we have many new features added to windows 7.One of the great feature that other windows versions does not posses is the ability to install and create themes.Themes play significant role in shaping the design of desktop.In earlier windows versions,even though it was possible to install themes,the choice of wallpapers,logon sound etc were chosen only by theme designers.It was difficult for everyone to design a theme since it is very complicated process.Now windows 7 gives its users freedom to install and create themes on their own.Also windows 7 has got an advantage to change the background wallpaper automatically.
