How would I go about changing the taskbar on that theme to a dark, 3-D convex taskbar like Windows Vista used to have?
In Short: -You need an application like
Photoshop or similar and then use various
effects and colouring techniques to get the desired result. Then
save it as a Png image in the same size as the first Taskbar was and then
Import it into Skinstudio in the Horizontal Taskbar area
