Just got word today that a Windows Live Essentials Beta is on the way, but what is Windows Live Essentials, well it’s an upcoming product which we can consider to be the Windows Live equivalent of the Google Pack, here’s a better description:

Windows Live is a new wave of online services-including e-mail, instant
messaging, and security- designed to work together as a seamless whole.
Windows Live Essentials is a simple way to get a set of these services
in one easy download. It’ll also give you Windows Live Dashboard, which
offers a handy view of what services you already have and what new ones
are available.

Included in this pack are sure to be Windows Live Messenger and Windows Live Mail Desktop along with other popular Windows Live Products.
