Security updates are available from Microsoft Update and Windows Update. Security updates are also available at the Microsoft Download Center. You can find them most easily by doing a keyword search for "security update".

Finally, security updates can be downloaded from the Microsoft Update Catalog. The Microsoft Update Catalog provides a searchable catalog of content made available through Windows Update and Microsoft Update, including security updates, drivers and service packs. By searching using the security bulletin number (such as, "MS07-036"), you can add all of the applicable updates to your basket (including different languages for an update), and download to the folder of your choosing. For more information about the Microsoft Update Catalog, see the Microsoft Update Catalog FAQ.

Note As of August 1, 2009, Microsoft discontinued support for Office Update and the Office Update Inventory Tool. To continue getting the latest updates for Microsoft Office products, use Microsoft Update. For more information, see About Microsoft Office Update: Frequently Asked Questions.

Detection and Deployment Guidance

Microsoft provides detection and deployment guidance for security updates. This guidance contains recommendations and information that can help IT professionals understand how to use various tools for detection and deployment of security updates. For more information, see Microsoft Knowledge Base Article 961747.

Microsoft Baseline Security Analyzer

The Microsoft Baseline Security Analyzer (MBSA) allows administrators to scan local and remote systems for missing security updates as well as common security misconfigurations. For more information about MBSA, visit Microsoft Baseline Security Analyzer.

Windows Server Update Services

By using Windows Server Update Services (WSUS), administrators can quickly and reliably deploy the latest critical updates and security updates for Microsoft Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 to Microsoft Windows 2000 and later operating systems.

For more information about how to deploy this security update using Windows Server Update Services, visit Windows Server Update Services.

Systems Management Server

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. The next release of SMS, System Center Configuration Manager 2007, is now available; see also System Center Configuration Manager 2007. For more information about how administrators can use SMS 2003 to deploy security updates, see SMS 2003 Security Patch Management. SMS 2.0 users can also use the Security Update Inventory Tool (SUIT) to help deploy security updates. For information about SMS, visit Microsoft Systems Management Server.

Note SMS uses the Microsoft Baseline Security Analyzer to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of SMS in these cases to target updates to specific systems. For more information about this procedure, see Deploying Software Updates Using the SMS Software Distribution Feature. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2.0 Administration Feature Pack) to install these updates.

Update Compatibility Evaluator and Application Compatibility Toolkit

Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit.

The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
