There are reports that two softwares will be available which installs features that are missing from Vista.
The first software is called Fiji which includes most of the features that Microsoft decided to remove from Vista such as Windows Live integration, a full-featured sidebar, the ability to playback High Definition DVD discs, a music software called Monaco, and a WinFS which is a file system (like FAT and NTFS).
Vienna is the name of the second software. It will include more features than Fiji and it is planned to be compatible with all applications.
