*Windows Server 2008 server core installation not affected. The vulnerabilities addressed by these updates do not affect supported editions of Windows Server 2008 if Windows Server 2008 was installed using the Server Core installation option, even though files affected by these vulnerabilities may be present on the system. However, users with the affected files will still be offered this update because the update files are newer (with higher version numbers) than the files that are currently on your system. For more information on this installation option, see Server Core. Note that the Server Core installation option does not apply to certain editions of Windows Server 2008; see Compare Server Core Installation Options.

Detection and Deployment Tools and Guidance
Security Central
Manage the software and security updates you need to deploy to the servers, desktop, and mobile computers in your organization. For more information see the TechNet Update Management Center. The TechNet Security Center provides additional information about security in Microsoft products. Consumers can visit Security At Home, where this information is also available by clicking “Latest Security Updates”.
Security updates are available from Microsoft Update, Windows Update, and Office 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.
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 (ESUIT). For more information, see Microsoft Knowledge Base Article 910723.
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 Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 to 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 Software Updates Services Feature Pack to help deploy security updates. For information about SMS, visit Microsoft Systems Management Server.
Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool 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 the 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 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
