First off you need to activate the Desktop Experience feature on 2008, to do this follow these steps
- Open the control panel (Start -> Control Panel)
- When the list of icons appears double click the Program and Features if you don’t see it you may need to click the Classic View link on the left hand pane
- When the Programs and Features page has loaded click the Turn windows features on or off link on the left hand pane (You may need to authorise this if you are using UAC)
- When the Server Manager screen appears click the Features item on the left hand pane and then click the Add Feature link on the right hand pane
- When the list of windows 2008 features appears make sure that the Desktop Experience item is ticked (If it’s already ticked you can skip the next part and just close the screens)
- Click Next and then Install you may be asked for the installation media at this point.
Once the above feature is activated then you’re nearly there, next you need to activate the Theme engine that provides the Aero features .
