Microsoft continues to develop the Windows Live services and the newest addition that they are working on is Windows Live Essentials which will compete with the Google Pack.
Much like the Google Pack they will be offering users a simple to use software bundle that will incorporate several different pieces of software. All of the software that Google offers is free with the exception of Norton AntiVirus 2005 in which you will receive a 6-month subscription.
You may probably see trials of Office or maybe they will just include the document viewers for each of the different Office programs. One guaranteed thing would be the Windows Live OneCare software to cover the security portion of the package just like how Google uses Norton.
I am eagerly awaiting the release of Windows Live Essentials.
