Office 2013 might be brand new, but its license agreement is already getting a significant upgrade. The new language represents a welcome change for buyers who prefer traditional licenses that don't require ongoing payments.
Bowing to "feedback from its customers," Microsoft is changing the terms of the license agreement for the three retail "perpetual license" versions of Office 2013, restoring the terms that had been present in the corresponding agreement for Office 2010. This means customers can transfer Office 2013 to a different computer if their device fails or they get a new one. Previously, customers could only transfer their Office 2013 software to a new device if their PC failed under warranty. While the license agreement accompanying Office 2013 software will be updated in a future release, this change is effective immediately and applies to Office Home and Student 2013, Office Home and Business 2013, Office Professional 2013 and the standalone Office 2013 applications. These transferability options are equivalent to those found in the Office 2010 retail license terms
Can I transfer the software to another computer or user? You may transfer the software to another computer that belongs to you, but not more than one time every 90 days (except due to hardware failure, in which case you may transfer sooner). If you transfer the software to another computer, that other computer becomes the "licensed computer." You may also transfer the software (together with the license) to a computer owned by someone else if a) you are the first licensed user of the software and b) the new user agrees to the terms of this agreement before the transfer. Any time you transfer the software to a new computer, you must remove the software from the prior computer and you may not retain any copies.
