Last week Microsoft made Windows Live Essentials 2011 available for download. This is a home consumer package for Windows Vista and 7. It contains new versions of Photo Gallery, Writer, Movie Maker, Messenger, Mail, and Outlook Connector Pack applications, and Windows Live Mesh, Family Safety, Messenger Companion, and Family Safety services.
You may download this package here: [explore.live.com...] (may require a Live ID to log in).
Isn't Windows Live Mesh like the old Live Mesh beta? There's no sync limit at all. The online option was always 5GB, but you could sync everything else between machines. I had many folders synced of photos, music and videos that well exceeded 5GB.
