Microsoft had first released Windows Live Essentials beta to the public on June 24 and the last beta was out on August 17. Live Essentials for Windows 7 and Vista has Windows Live Movie Maker, Mail, Messenger, Writer, Mesh (formerly known as Sync), Family Safety, Photo Gallery, Messenger Companion, Bing Bar, Outlook Connector Pack and Silverlight. All applications now use the new ribbon UI and integrate further into Windows 7 by using Jumplists.
Windows Live Essentials 2011 is only compatible with 32-bit and 64-bit editions of Windows Vista and Windows 7, and the Windows Server 2008 releases. Windows XP users are stuck with the 2010 releases of Windows Live.
