\*The Updates Replaced column shows only the latest update in a chain of superseded updates. For a comprehensive list of updates replaced, go to the [Microsoft Update Catalog](http://catalog.update.microsoft.com/v7/site/home.aspx), search for the update KB number, and then view update details (updates replaced information is on the **Package Details** tab). Update FAQ ---------- **Why are some of the updates listed in this bulletin also denoted in other bulletins releasing this month?** Since bulletins are broken out by the security vulnerabilities they address, not by the update packages being released, it is possible for separate bulletins to reference the same update if the fixes for their respective vulnerabilities have been consolidated into a single update package. In such situations it is also possible for the vulnerabilities described in the one bulletin to have completely different severity and impact ratings than the vulnerabilities described in the other bulletin. This is frequently the case with cumulative updates for products such as Internet Explorer or Silverlight where singular updates contain fixes for very different security vulnerabilities being discussed in separate bulletins. Note that identical update files shipping with multiple bulletins do not need to be installed more than once. **There are multiple update packages available for some of the affected software. Do I need to install all the updates listed in the Affected Software table for the software?** Yes. Customers should apply all updates offered for the software installed on their systems. If multiple updates apply, they can be installed in any order. **Do I need to install these security updates in a particular sequence?** No. Multiple updates for a given system can be applied in any sequence. **I am running Office 2010, which is listed as affected software. Why am I not being offered the update?**  The update is not applicable to Office 2010 on Windows Vista and later versions of Windows because the vulnerable code is not present. **I am being offered this update for software that is not specifically indicated as being affected in the Affected Software and Vulnerability Severity Ratings table. Why am I being offered this update?** When updates address vulnerable code that exists in a component that is shared between multiple Microsoft Office products or shared between multiple versions of the same Microsoft Office product, the update is considered to be applicable to all supported products and versions that contain the vulnerable component. For example, when an update applies to Microsoft Office 2007 products, only Microsoft Office 2007 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2007, Microsoft Excel 2007, Microsoft Visio 2007, Microsoft Compatibility Pack, Microsoft Excel Viewer, or any other Microsoft Office 2007 product that is not specifically listed in the Affected Software table. Furthermore, when an update applies to Microsoft Office 2010 products, only Microsoft Office 2010 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2010, Microsoft Excel 2010, Microsoft Visio 2010, Microsoft Visio Viewer, or any other Microsoft Office 2010 product that is not specifically listed in the Affected Software table. For more information on this behavior and recommended actions, see [Microsoft Knowledge Base Article 830335](https://support.microsoft.com/kb/830335). For a list of Microsoft Office products an update may apply to, refer to the Microsoft Knowledge Base Article associated with the specific update. **Are there any prerequisites for any of the updates offered in this bulletin for affected editions of Microsoft Lync 2013 (Skype for Business)?** Yes. Customers running affected editions of Microsoft Lync 2013 (Skype for Business) must first install the 2965218 update for Office 2013 released in April, 2015, and then the 3039779 security update released in May, 2015. For more information about these two prerequisite updates, see: -
