Microsoft Windows Live OneCare is a comprehensive and integrated PC health service that helps protect and maintain your computer with antivirus, firewall, PC maintenance, and file backup and restore functionality. This new service is in beta testing.

New features we should be seeing include:
* Multi PC management - designate a hub PC and then add additional PCs to your OneCare circle using a common Windows Live ID. You can then see the status of the other PCs within the group.
* Printer Sharing - share your printer with all the PCs in your OneCare circle
* OneCare Online Photo Backup - paid storage is available online for photo backups (we're hearing 10GB but that could change by the end of the beta)
* Securing wireless networks - if your router is supported OneCare 2.0 will allow you to secure your wireless network
* x64 support
