Update information

Detection and deployment tools and guidance

Security Central

You can manage the software and security updates that you have 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 website provides additional information about security in Microsoft products.

Security updates are available from

Microsoft Update and

Windows Update. Security updates are also available from the

Microsoft Download Center. You can find security updates most easily by doing a keyword search for "security update."

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 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

Microsoft 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.

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

Software

MBSA

Windows 8 and Windows 8.1 for 32-bit systems

No

Windows 8 and Windows 8.1 for 64-bit systems

No

Windows Server 2012 and Windows Server 2012 R2

No

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 Services

Windows 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 article:

Windows Server Update Services

Systems Management Server

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

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 customers remaining on SMS 2003 Service Pack 3, the

Inventory Tool for Microsoft Updates (ITMU) is also an option.

For SMS 2003, the SMS 2003 Inventory Tool for Microsoft Updates (ITMU) can be used by SMS to detect security updates that are offered by

Microsoft Update and that are supported by

Windows Server Update Services. For more information about the SMS 2003 ITMU, see

SMS 2003 Inventory Tool for Microsoft Updates. For more information about SMS scanning tools, see

SMS 2003 Software Update Scanning Tools. See also

Downloads for Systems Management Server 2003.

System Center Configuration Manager uses WSUS 3.0 for detection of updates. For more information, see

System Center.

For 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 validating of Windows updates against installed applications by using the

Update Compatibility Evaluator components that are included with


Application Compatibility Toolkit.

The Application Compatibility Toolkit (ACT) 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.

Verifying that the update was applied

Because 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.

File version verification

  1. Click Start, and then type an update file name in the Search box.

  2. When the file appears under Programs, right-click the file name, and then click Properties.

  3. On the General tab, compare the file size with the file information tables that are provided in the Microsoft 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.
