Windows Live Essentials is an upcoming product that will be the Windows Live equivalent of the Google Pack; allowing for one-click installations as well as providing update notifications for the individual products. With a central control panel (Windows Live Dashboard) providing information on the various Windows Live application, Essentials should eventually allow automated installations.
While the product won’t necessarily be used by the more technically advanced users, especially those in the betas, it will no doubt benefit the vast majority.
Essentials also has some pluses for Microsoft. Smaller Windows Live products can take advantage of increased exposure and applications are more likely to stay current. There is also the “small” benefit of getting Windows Live products preinstalled on Vista machines via OEMs, as Google have done recently with their toolbar.
Update: We got confused with our names. Dashboard appears to be part of Windows Live Essentials. Post edited slightly to reflect this.
