Branding and customization
For original equipment manufacturers and enterprises, Windows 7 natively supports the ability to customize the wallpaper that is displayed during user login. Because the settings to change the wallpaper are available via the Windows Registry, users can also customize this wallpaper.[15] Options to customize the appearance of interface lighting and shadows are also available.
Federated search
Windows Explorer also supports federating search to external data sources, such as custom databases or web services, that are exposed over the web and described via an OpenSearch definition. The federated location description (called a Search Connector) is provided as an .osdx file. Once installed, the data source becomes queryable directly from Windows Explorer. Windows Explorer features, such as previews and thumbnails, work with the results of a federated search as well.
Miscellaneous shell enhancements
Windows Explorer has received numerous minor enhancements that improve its overall functionality. The Explorer’s search box and the address bar can be resized. Folders such as those on the desktop or user profile folders can be hidden in the navigation pane to reduce clutter. A new Content view is added, which shows thumbnails and metadata together. A new button to toggle the Preview Pane has been added to the toolbar. The button to create a new folder has been moved from the Organize menu and onto the toolbar. List view provides more space between items than in Windows Vista. Finally, storage space consumption bars that were only present for hard disks in Windows Vista are now shown for removable storage devices.
Start menu
The start button now has a fade-in highlight effect when the user hovers over it with the mouse cursor. The right column of the Start menu is now prominently the Aero Glass color; in Windows Vista, it was predominantly black regardless of the color in use.
