How to Install the New MSN for Free
MSN Messenger is now Windows Live. This service is a social networking service that incorporates Hotmail and MSN Messenger into one network. Windows Live Messenger is free and can be used in your browser when logging into your Hotmail email account, or you can download the latest version for free on Microsoft's website. Once you download the latest version, it will replace whatever version of MSN you have downloaded on your computer.
Visit Windows Live's website and click "Download Now."
Save the executable file to your computer. Run the wizard completely, reading through each screen and choosing "Next."
Restart your computer upon completion of the installation wizard. Log in using your email address and password.
