First of all you need to search for Universal Theme Patcher - it will allow to apply different styles to your win7. Specifically in this ss i've used: [link] (or it's predecessor). But there're many other beautiful styles as well - search the site. To apply the style in the most convenient way you need theme manager for windows 7 (google it). Docks are coming from Object Dock application. The style is Peru Adium (you can find it in my gallery). It's worth to say that there're many others. OD isn't free. The alternatives: RocketDock, XWindows dock. But both do not have tabs setup. For small player in the bottom right corner you need CAD application (google it). The style is Peru Adium - search deviantart for it. The big player is iTunes (apple it ). The great number of styles you could find at daviantart. Icon you can get as well at deviantart - the taskbar setup is manual but there is an application for this purpose: 7conifier.
