The cumulative update packages for December 2014 contain the latest hotfixes for Microsoft Office 2010 and for the Office 2010 servers.

We recommend that you test hotfixes before you deploy them in a production environment. Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous update package. We recommend that you consider applying the most recent fix release that contains the hotfix that you need.

How to obtain the December 2014 cumulative update packages

A set of supported cumulative update packages are now available from Microsoft. However, each package is intended to correct only the applications that are listed in this article. Apply the packages only to systems that are experiencing these specific problems. If you are not severely affected by any of these problems, we recommend that you wait for the next update package that contains the hotfixes in these cumulative update packages.

Note If additional issues occur or any troubleshooting is required, you might have to create a separate service request. The usual support costs will apply to additional support questions and issues that do not qualify for a specific cumulative update package. To create a separate service request, visit the following Microsoft website:
