Detection and Deployment Tools and Guidance

Manage the software and security updates you need to deploy to the servers, desktop, and mobile systems in your organization. For more information see the TechNet Update Management Center. The Microsoft TechNet Security Web site provides additional information about security in Microsoft products.

Security updates are available from Microsoft Update, Windows Update, and Office Update. Security updates are also available from 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.

Detection and Deployment Guidance

Microsoft has provided detection and deployment guidance for this month’s security updates. This guidance will also help IT professionals understand how they can use various tools to help deploy the security update, such as Windows Update, Microsoft Update, Office Update, the Microsoft Baseline Security Analyzer (MBSA), the Office Detection Tool, Microsoft Systems Management Server (SMS), and the Extended Security Update Inventory Tool. For more information, see Microsoft Knowledge Base Article 910723.

Microsoft Baseline Security Analyzer

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.

The following table provides the MBSA detection summary for this security update.

Software MBSA 2.1

Microsoft Office 2000 Service Pack 3

No

Microsoft Office XP Service Pack 3

Yes

Microsoft Office 2003 Service Pack 2

Yes

Microsoft Office Converter Pack

Microsoft Works 8

Yes*

*Note If the system uses Microsoft Update for update scanning and can access Microsoft Update (which a scan report can determine), MBSA 2.1 will detect Microsoft Works 8. However, if the system is managed by WSUS or is in an offline secure environment, which forces the system to use the WSUSSCN2.CAB offline catalog, MBSA 2.1 will not detect Microsoft Works 8.

For more information about MBSA 2.1, see MBSA 2.1 Frequently Asked Questions.

Note For customers using legacy software not supported by MBSA 2.1, Microsoft Update, and Windows Server Update Services: please visit Microsoft Baseline Security Analyzer and reference the Legacy Product Support section on how to create comprehensive security update detection with legacy tools.

Windows Server Update Services

By using Windows Server Update Services (WSUS), administrators can deploy the latest critical updates and security updates for Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000. For more information about how to deploy this security update using Windows Server Update Services, visit the Windows Server Update Services Web site.

For more detailed information, see Microsoft Knowledge Base Article 910723: Summary list of monthly detection and deployment guidance articles.

Note If you have used an Administrative Installation Point (AIP) for deploying Office 2000, Office XP or Office 2003, you may not be able to deploy the update using SMS if you have updated the AIP from the original baseline. For more information, see the Office Administrative Installation Point heading in this section.

Office Administrative Installation Point

If you installed your application from a server location, the server administrator must update the server location with the administrative update and deploy that update to your system.

•

For supported versions of Microsoft Office 2000, see How to Create an Administrative Installation Point. For more information about how to change the source for a client system from an updated administrative installation point to an Office 2000 Service Pack 3 (SP3), see Microsoft Knowledge Base Article 932889.

Note If you plan to manage software updates centrally from an updated administrative image, you can find more information in the article Updating Office 2000 Clients from a Patched Administrative Image.
•

For supported versions of Microsoft Office XP, see Creating an Administrative Installation Point. For more information on how to change the source for a client system from an updated administrative installation point to an Office XP original baseline source, see Microsoft Knowledge Base Article 922665.

Note If you plan to manage software updates centrally from an updated administrative image, you can find more information in the article Updating Office XP Clients from a Patched Administrative Image.
•

For supported versions of Microsoft Office 2003, see Creating an Administrative Installation Point. For more information on how to change the source for a client computer from an updated administrative installation point to an Office 2003 original baseline source or Service Pack 2 (SP2), see Microsoft Knowledge Base Article 902349.

Note If you plan to manage software updates centrally from an updated administrative image, you can find more information in the article, Distributing Office 2003 Product Upgrades.

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 5.0.

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.
