Here it is! the one thing that Windows users have been waiting for so long. The Windows Live Essentials 4 has been leaked on the web.
Unfortunately! this build is only limited to certain beta testers so all the different applications can't be used. However, a patch has been created to allow users to use the new Windows Live Messenger in Wave 4.
Features include: different views in Messenger (social and expanded contacts). This is an early release and the final version may have more features. Follow the link to the full installer and the Messenger patch to get this up and running.
