I believe a clean install is what you would need to do to go back to Starter. However, I am not sure why you would want to go back. Using the Anytime Upgrade option from Windows will just give you access to more features while maintaining the same quality system that you currently have with Starter (including the ability to change your desktop background...which is a big plus for me :))!
