Your original Windows theme still exists. You simply need to restore it.
PC desktops are as unique as the individuals who own them. To give computer users the ability to customize Windows, Microsoft created "themes." A theme is a set of sounds, colors, screen savers and images that define a particular look. Install new themes or create your own collections to achieve a look that defines your personality and preferences. When you want to restore the original Windows look, you can reset the default theme without deleting others in your themes collection.
