updates, service packs, and update rollups known collectively as high priority updates.

Security Essentials
Automating Your Updates
Windows updates are not distributed on a regular basis. Instead, they re published when the need arises, such as when a patch is developed for a newly discovered security vulnerability. In Windows XP, you can eliminate the necessity to check for updates manually by using a feature called Automatic Updates. With this feature enabled, you can instruct Windows to periodically check for high priority updates. Using the preferences you define, Automatic Updates checks for new high priority updates, downloads them in the background, using a small segment of your available Internet connection bandwidth, and with your permission installs them automatically. Note Automatic Updates retrieves only high priority updates. To view, download, and install other Windows updates and newly released drivers, you need to visit the Windows Update site. Each Windows XP Service Pack has included a major overhaul of the Automatic Updates feature, and Service Pack 2 is no exception. In the original release of Windows XP, you could choose to be alerted when new updates were available, and Windows would download them for you to install, but the operating system wouldn t actually perform the updates. With SP2 installed, the Automatic Updates dialog box includes new options, including the ability to install high priority updates on a specified schedule. After you first install Windows XP, the operating system is persistent about reminding you to set up the Automatic Updates feature. You can adjust the related options at any time by opening Automatic Updates, which you can do in any of the following ways:
Open Security Center and click Automatic Updates. (For more information about
Security Center, see Monitoring Windows XP Security, page 170.)
Open System in Control Panel (in the Performance And Maintenance group) and click
the Automatic Updates tab.
Open Automatic Updates in Control Panel (if you use Classic view). Enter wuaucpl.cpl at a command prompt or open a shortcut to this command.
To enable Automatic Updates, select one of the first three options available to you, as shown in Figure 6-12:
Automatically Download Recommended Updates For My Computer And Install
Them Choose this option if you want the Automatic Updates process to live up to its name completely. In this set it and forget it configuration, Windows Update checks for high priority updates on the schedule you specify (by default at 3:00 A.M. every day, although you can change the schedule to weekly and change the time as well), downloads each one as soon as it appears, and installs the update for you. Beware, however: If an update requires restarting your computer, Windows will do so with no regard to whether any applications are open. This option is most appropriate if you leave your computer turned on.

Download Updates For Me, But Let Me Choose When To Install Them
This option is most appropriate for users with high-speed, always-on Internet connections cable modems and DSL, for instance. An icon in the notification area alerts you when a download has arrived. You can accept or reject any download. If you don t want to tie up your dial-up Internet connection downloading updates, choose this option. An icon in the notification area alerts you when a download is available; you decide whether and when to download and install it.
