Windows Live is a new set of Internet software and services designed to put you in control of the information, relationships, and interests that you care about. Windows Live makes it easier for you to connect with people, and to find the information that you need, more quickly, safely, and securely, whether you're on your computer or on the go. And it's evolving every day—with your feedback, it'll just keep getting better. You can try out the latest Windows Live sites and services on the http://download.live.com website.
Don't worry, ninemsn isn't going away. It's still a great place to get content, news, and information, and you can still get the e-mail, instant messaging, and search services that you know and love.
