Microsoft has previewed the first major upgrade to Windows Live Essentials for Windows 7.

Windows Live Essentials is a suite of free programs, including Photo Gallery, Movie Maker, Messenger, Sync, and Mail. Microsoft says the tools have over 500 million daily users.

Photo Gallery now adds facial recognition and sorting to existing tools like quick Auto Adjust and Retouch. Another new feature, Photo Fuse, lets you take the best parts from similar pictures and fuse them together.

Movie Maker now has "AutoMovie" themes, which lets you easily apply snazzy themes, visuals, text, and other effects to your movies. You can then export your videos in HD formats, also a new feature. You're also able to share videos across Flickr, Facebook, and other sites.

The Email program lets you manage multiple email accounts, calendars, RSS feeds, contacts and newsgroups all in one place. New features include: sending up to 10GB of photos per email, instant messaging in the inbox, conversation threading and more.

You can also use the Sync feature which to automatically sync an updated folder from one computer to another when they're turned on.

Using the new remote desktop feature, you can also sync to other computers via an Internet connection, or view files on another computer from a remote device. If the computers are turned off, you can store the information online and the computers will sync when they are turned on.

These are only a fraction of the available features available. You can try download the full suite or just certain programs at http://download.live.com.
