Renaming != killing.
The names we used to describe our products added to that complexity: we used "Windows Live" to refer to software for your PC (Windows Live Essentials), a suite of web-based services (Hotmail, SkyDrive, and Messenger), your account relationship with Microsoft (Windows Live ID), and a host of other offers.
Windows 8 provides us with an opportunity to reimagine our approach to services and software and to design them to be a seamless part of the Windows experience, accessible in Windows desktop apps, Windows Metro style apps, standard web browsers, and on mobile devices. ...
it is all included when you turn on your PC for the first time.
