After discussion last week that Windows Live OneCare 1.6 had been released, it is now available to all users from onecare.live.com. Users already running OneCare will be upgraded over the next few weeks, however you may prefer not to wait. Changes in 1.6 include the ability to disable the firewall permanently (Firewall - Firewall Advanced Settings - Managing and Sharing) or for a certain period of time (slide the firewall slider to the bottom) as well as a monthly report of firewall activity available from the OneCare dashboard.
微软推出的杀毒软件，套件包括反病毒防火墙、数据备份、反间谍、磁盘清理等功能。提供90天试用。这款软件在Vista还刚刚通过了VB100的测试，中文版的系统需要修改注册表语言选项来支持这一软件：
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Nls\Language]
"InstallLanguage"="0804"
"Default"="0804"
将其中的0804改为0409，就是英文了！
