More Information

Important

All future security and non-security updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require update 2919355 to be installed. We recommend that you install update 2919355 on your Windows RT 8.1-based, Windows 8.1-based, or Windows Server 2012 R2-based computer so that you receive future updates.
If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you require before you install this update. For more information, see Add language packs to Windows.
This security update applies to the Windows operating systems that are listed in the "Applies to" section in this article. If you want to install Adobe Flash Player update on an earlier version of Windows, try Adobe Flash Player Download.

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, and Windows Server Update Services should see the "Legacy Product Support" section of Microsoft Baseline Security Analyzer. Here, they will 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 ToolkitUpdates 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 decrease 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.
