We’ve always known customers love personalizing their Windows experience. At the center of this expression of individuality are ingredients such as the desktop background, glass color, sounds and screensavers. In Windows 7 we’ve introduced themes that make it easy to enable a whole package of default combinations or for customers to save their own creations. However, during Beta we heard feedback along the lines of “I just changed my background or color and I see the change, but I thought it was saved when it really wasn’t”.
