If you are logged on as an administrator, the Automatic Updates feature in Microsoft Windows XP notifies you when critical updates are available for your computer. You can also specify the schedule that Windows follows to install updates on your computer. This article describes how to configure the Automatic Updates features in Windows XP.

Note This article assumes that you are using the latest Automatic Updates feature. Automatic Updates is included with Windows XP Professional, Windows XP Home Edition, and Windows XP 64-Bit Edition, but the latest Automatic Updates feature is included with Windows XP Tablet PC Edition Service Pack 2 (SP2), Windows XP Media Center Edition SP2, and Windows XP Professional SP2, Windows XP Home Edition SP2, and Windows XP 64-Bit Edition SP2.

If you use Automatic Updates with Windows XP Professional, Windows XP Home Edition, and Windows XP 64-Bit Edition, the feature may have been automatically updated on your computer. If the options that are described in step 2 of the Turn On and Use Automatic Updates section are not available, install Windows XP SP2 to obtain the latest Automatic Updates feature. For more information about how to obtain SP2, click the following article number to view the article in the Microsoft Knowledge Base:

Change the Settings for Automatic Updating

To change the settings for Automatic Updates, use the Automatic Updates tab in System Properties as described in the appropriate sections later in this article. In Windows XP Home Edition, you must be logged on as a computer administrator to install components or modify Automatic Updates settings. In Windows XP Professional, you must be logged on as an administrator or a member of the Administrators group. If your computer is connected to a network, network policy settings may prevent you from completing these procedures.

Windows may prompt you to restart your computer after certain components are installed. Restart your computer when prompted; otherwise, your computer might not work correctly.

Advanced users and IT Professionals can configure Automatic Updates by using Group Policy in an Active Directory environment, or by using registry settings in a non-Active Directory environment.

Update Your Files by Using Windows Update or by Using Microsoft Update

If you choose not to use Automatic Updates, you can still install specific updates from the Windows Update Web site or from the Microsoft Update Web site. Windows Update and Microsoft Update are catalogs of items such as drivers, security fixes, critical updates, the latest Help files, and Internet products that you can download to keep your computer up-to-date.

To update your system files with the latest critical updates by using the Windows Update Web site or by using the Microsoft Update Web site, follow these steps:

1.	Start Microsoft Internet Explorer.
2.	On the Tools menu, click Windows Update.
3.	Click Yes if you are prompted to install any required software. The Windows Update home page or the Microsoft Update home page appears.
4.	Click Express Install (Recommended): High Priority Updates for Your Computer. Windows Update or Microsoft Update looks for any critical updates that are available for your computer.
5.	Click Install to install all available critical updates.

You can also search the Windows Update Catalog or the Microsoft Update Catalog to find updates that you can download and install later on one or more computers that run Microsoft Windows 98, Microsoft Windows Millennium Edition, Microsoft Windows 2000, Windows XP, and Microsoft Windows Server 2003 across your home or corporate network. We recommend that only advanced users and administrators download updates from the Windows Update Catalog or from the Microsoft Update Catalog.
