Windows Update is the online extension of Windows. Use Windows Update to download items such as security fixes, critical updates, the latest Help files, drivers, and Internet products. New content is added to the site regularly, so you can always get the most recent updates and fixes to protect your computer and keep it running smoothly. For more information, see Windows Update at the Microsoft Web site. Also, see Using Windows Update.
With Windows Update Catalog, you can select updates that you plan to deploy later, which means you can control how and when the updates are deployed. For more information, see Windows Update Catalog at the Microsoft Web site.
With Automatic Updates, which is built into Windows XP and products in the Windows Server 2003 family, the operating system can automatically download and install critical updates from the Windows Update site. For more information, see Automatic Updates.
With Microsoft Windows Update Services, you can deploy a limited version of the Windows Update site inside your firewall. You can control how and when updates are deployed, and deliver updates to users through your intranet rather than having updates occur directly from the Internet. For more information about Windows Update Services, see Evaluate Windows Update Services Now at the Microsoft Web site.
