A new report claims to have details of Microsoft's offer that will allow owners of Office 2010 to update their software to the recently announced new version Office 2013.

Microsoft Wednesday removed its Office Update 2013 (KB2817630), which was released Tuesday as part of the company's regularly monthly release of patches.

Kurt DelBene, the leader of Microsoft's Office division, hinted this week that we could see updates for both Office 365 and the client-based Office 2013 software every three months.

Microsoft has launched an Office upgrade offer that gives customers who purchase the current Office 2010 a free copy of the upcoming Office 2013.
