Microsoft Office 2013 is the follow-up to Microsoft's Office 2010 office suite. Office 2013 has been developed under the Office 15 codename, as it will be the fifteenth release of the ubiquitous office suite.
Microsoft released a consumer preview of Office 2013 in July 2012, and the official release of Microsoft Office 2013 is expected in the second half of 2012, at about the same time as the debut of Windows 8. Office 2013 will only support Windows 7 and Windows 8 operating systems, with a separate version of Office 2013 integrated in ARM-based tablets running Microsoft Windows RT, including Microsoft's own Surface tablet.
Microsoft Office 2013 will be available in the traditional box software format as well as by download and also through Office 365, Microsoft's subscription-based Office Web Apps service. The new Microsoft Office release will be optimized for Windows 8 and its Metro interface as well as for touchscreen use, cloud computing via Microsoft's SkyDrive, and tablet devices. One important change in Microsoft Office 2013 is that by default Office 2013 files will be saved to the SkyDrive cloud instead of locally.
