Office 2010

Office 2010 is a version of Microsoft Office, released on 2010-04-25. New features include newer PowerPoint animation effects, new splash screens, ribbon interface in every application (in Office 2007, the ribbon was only included in Word, Access, PowerPoint, and Excel).

The final build number is 14.0.4760. Many torrents and even OEMs distribute build 4734 (which is not the final RTM build), as "RTM".

Office 2010 is the first version to have an x64 variant, though the x64 variant has some limitations. The x86 version requires XP SP3 or newer. The x64 version requires Vista SP1 or newer and is officially not supported on XP x64 edition, though it can be tricked to install on XP x64 fine.

System requirements
Only x86 edition of Windows XP SP3 is supported, but the installer can be tricked to run on the x64 edition correctly. Using Extended Kernel, this can also theoretically run on Windows 2000, though you may encounter some bugs (like Office 2007). Unofficially, this is the last version of Office that supports Windows 2000.

Click to Run
Office 2010 includes a new "Click to Run" (C2R) installer as an alternative to the old MSI installer, it is used in the starter SKU and available for home and business/home and student editions.
