The MS Office 2013 productivity software suite is Microsoft's new version of Office to go with Windows 8. As such, it has an interface optimized for touch and features some of the tiled look of Windows 8. In line with Microsoft's effort to encourage customers to upgrade from older versions of Windows, the new Office version no longer runs on Windows XP and Windows Vista.
Compared to the previous version, Office 2010, Microsoft has left the file formats unchanged and has kept almost all functions working as they did before. A few, such as AutoCorrect, are slightly harder to access. The new Office suite includes several added features in formating documents, improved PDF file handling and a better integration with online services such as Office 365 and SkyDrive. If you find that one of the specific changes listed below will improve the way you work, it may be worthwhile to upgrade.
