One of the most important things you can do to protect your computer and the data on it from hackers, viruses, worms, and other malware is to keep your system software up to date by running Microsoft's Windows Update feature. Windows Update is the mechanism by which Microsoft provides updates to its operating systems, distributing service packs and critical updates that either fix problems in Windows, or protect against known vulnerabilities in Windows or Internet Explorer.
You should run Windows Update and download all available critical updates at least once a week, or configure Windows Update to run automatically. Another easy way you can update your software is to use the Internet Explorer browser and go to the Windows Update web site at: http://windowsupdate.microsoft.com/ Follow the directions given and they will lead you through the steps required to get the latest updates. Microsoft never distributes service packs or critical updates via email - they require that you come to their web site and download them.
