This article describes update 2878252 for Microsoft Office 2010 that was released on July 8, 2014.

This update provides the latest fixes for Office 2010. This update improves the round-trip behaviors of modern shapes into legacy shapes and back again between file formats of the 2007 Office system and Office 2003. It also includes stability and performance improvements.

Issues that the update resolves

  • When you open a document from a web server that accepts or requires client certificates, you are prompted to select the certificate even though there is just one valid certificate available for client authentication.
    You expect that files open directly if there is exactly one certificate available for the user.

  • Assume that a certificate authorization is required for a document. When you use an Office 2010 application to open the document in a web browser, the browser stops responding.
