This is an update to Microsoft Office Word 2007. Generally, customers who purchase or license Word 2007 from Microsoft after January 10, 2010 for use in the United States and its territories must use updated software that does not include a particular custom XML tagging implementation.

You must install this update if you are instructed by Microsoft in a separate communication.

For technical details on the affected custom XML tagging functionality, please see KB978951.

The version 2 update to the patch is to improve interoperability with the April 2010 and future Cumulative Updates for Word 2007
