In all other regions, retail copies of Office 2013 and Office 365 subscriptions only contain a product key, and direct users to the Office website to redeem their license and download the software.
However, on March 6, 2013, Microsoft announced that equivalent transfer rights to those in the Office 2010 retail license agreements are applicable to retail Office 2013 copies effective immediately.
Transfer of license from one computer to another owned by the same user is now allowed every 90 days, except in the case of hardware failure, in which the license may be moved sooner.
Microsoft Office 2013 includes updated support for ISO/IEC 29500, the International Standard version of Office Open XML (OOXML) file format: in particular it supports saving in the "Strict" profile of ISO/IEC 29500 (Office Open XML Strict).
Additionally, Office 2013 provides full read, write, and edit support for ISO 32000 (PDF).
