If you have installed a preview version of Windows 7 Ultimate (e.g. beta, release candidate build 7100 or RTM build 7600) and want to install a cheaper version of Windows 7 Home Premium or Professional the installation is normally refused.
But with change of a registry key whilst installation you can fake a minor version - so you can install Home Premium or Professional over existing Windows 7 Ultimate.
