Microsoft Office 2010, codenamed Office 14, is a productivity suite for Microsoft Windows,[2] and is the successor of Microsoft Office 2007 for Microsoft Windows. Office 2010 includes extended file compatibility,[3] user interface updates,[4] and a refined user experience.[5][6] It will be available for Windows XP SP3 (32-bit), Windows Vista SP1 and Windows 7.[7] With the introduction of Office 2010, a 64-bit version of Office[8] will be available for the first time, although only for Windows Vista SP1, Windows Server 2008 SP1, Windows 7 and Windows Server 2008 R2.[9] Office 2010 is not supported on Windows XP Professional x64 Edition. [10]

Microsoft has confirmed that Office 2010 will be released in the first half of 2010[11] (May 12th RTM, General Availability in June),[12] and a public beta was made available in November 2009.[13]

Office 2010 will mark the debut of free online versions of Word, Excel, PowerPoint, and OneNote, which will work in popular web browsers (Internet Explorer, Mozilla Firefox, Google Chrome, and Apple Safari). A new edition of Office, Office Starter 2010, will replace the current low-end home productivity software, Microsoft Works.

Microsoft's update to its mobile productivity suite, Office Mobile 2010, will also be released for Windows Phones running Windows Mobile 6.5 and Windows Phone 7. In Office 2010, every application has the Ribbon, including favorites such as OneNote 2010, Publisher 2010, InfoPath 2010, SharePoint Workspace 2010 (the new name for Microsoft Office Groove 2007) and the new Office Web Apps.

A new feature in Microsoft Office 2010 is the Social Connector. This allows users to write emails while keeping track of their family, friends and colleagues by viewing status updates and past communication history with the individual. When users view their emails a name, picture, and title will be available for the person they are contacting. Upcoming appointments can also be viewed with this new feature and users can request friends.
