changing the segmented green progress bar in xp

How can someone change the unattractive segmented green progress bar in windows xp to the solid green progress bar in Vista.The solid green color looks much better than the thin white vertical line that is in each of the green segements of the xp progress bar [ie. the loading indicator status bar]. has a written text program for changing it and includes an explanation for each line of the program.There is also a free download of the source code but the adobe 8 reader on my computer says it is unable to open the files.Does anyone know of any other links that offer the program?
