Graphics Properties opens up Intel(R) Graphics and Media Control Panel and I can't figure out how to change it there.
If this is Windows 7, when you right click the desktop you should get a menu which contains an item "Personalize". If you click this you should get a window titled "Personalization". At the bottom is a row of icons, one of which will be titled "Window Color". If you click this you get a window titled "Window Color and Appearance". The lowest item is a clickable link "Advanced appearance settings...". Click this and you finally get this dialog in which you can access most of the visual elements of the Windows GUI. The "Item" dropdown is the key.
The other way to get to the Personalization dialog is the Display control panel applet - in the Display dialog look for "See also" in the bottom left corner, under that is a link name "Personalization".
