Windows Vista Ultimate also offers Windows Ultimate Extras, free downloads that extend functionality or provide new features.

Windows Vista Business

This edition is intended for businesses of all sizes. It does not feature the media capabilities of Windows Vista Home Premium but does include the Windows Aero user experience.

It also includes several features important to businesses, such as advanced backup features and Remote Desktop.
