More Information

Security CentralYou can manage the software and security updates that you have to deploy to the servers, desktops, and mobile systems in your organization. For more information, see the TechNet Update Management Center. The Microsoft TechNet Security website provides more information about security in Microsoft products.

You can download security updates from the
Microsoft Update Catalog. The Microsoft Update Catalog provides a searchable catalog of content that is made available through Windows Update and Microsoft Update. This includes security updates, drivers, and service packs. For more information about the Microsoft Update Catalog, see the Microsoft Update Catalog FAQ.

Detection and deployment guidanceMicrosoft 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 AnalyzerMicrosoft Baseline Security Analyzer (MBSA) lets administrators scan local and remote systems for missing security updates and common security misconfigurations. For more information, see Microsoft Baseline Security Analyzer.

Note Customers who use legacy software that is not supported by the latest release of MBSA, Microsoft Update, or Windows Server Update Services should see the "Legacy Product Support" section of Microsoft Baseline Security Analyzer. Here, you can find information about how to create comprehensive security update detection by using legacy tools.

Windows Server Update ServicesWindows Server Update Services (WSUS) lets information technology administrators deploy the latest Microsoft product updates to computers that are running Windows. For more information about how to deploy security updates by using Windows Server Update Services, see the following Microsoft TechNet topic:

Windows Server Update Services

Systems Management ServerThe following table provides the Microsoft Systems Management Server (SMS) detection and deployment summary for this security update.

Software	SMS 2003 with ITMU	System Center Configuration Manager
Windows 8.1 for 32-bit systems	No	Yes
Windows 8.1 for 64-bit systems	No	Yes
Windows Server 2012 and Windows Server 2012 R2	No	Yes

Note Microsoft discontinued support for SMS 2.0 on April 12, 2011. For SMS 2003, Microsoft also discontinued support for the Security Update Inventory Tool (SUIT) on April 12, 2011. Customers are encouraged to upgrade to System Center Configuration Manager.

For SMS 2003, the SMS 2003 Inventory Tool for Microsoft Updates (ITMU) can be used by SMS to detect security updates that are supported by Windows Server Update Services. For more information, see Systems Management Server 2003.

System Center Configuration Manager uses WSUS 3.0 to detect updates. For more information, see System Center.

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

Update Compatibility Evaluator and Application Compatibility Toolkit

Updates frequently write to the same files and registry settings that are required for your applications to run. This can trigger incompatibilities and increase the time that is required to deploy security updates. You can streamline the testing and validation of Windows updates against installed applications by using the Update Compatibility Evaluator components that are included in the Application Compatibility Toolkit (ACT).

The Application Compatibility Toolkit contains the necessary tools and documentation to evaluate and address application compatibility issues before you deploy Windows Vista, a Windows update, a Microsoft security update, or a new version of Windows Internet Explorer in your environment.

Verifying that the update was appliedBecause there are several editions of Windows, the following steps may be different on your system. If they are different, see your product documentation to complete these steps.

Verifying the file version

Click Start, and then type an update file name in the Search box.
When the file appears under Programs, right-click the file name, and then click Properties.
On the General tab, compare the file size to the size that is listed in the file information tables that are provided in this Knowledge Base article.

Note Depending on the edition of the operating system or the programs that are installed on your system, some files that are listed in the file information table may not be installed.
You can also click the Details tab to compare such information as file version and date changed to the information that is listed in the file information tables that are provided in the Knowledge Base article.

Note Attributes other than the file version may change during installation.
