Microsoft finally launched Microsoft Office 2010 and make it available for public download FOR FREE but it’s still in beta status and intentionally for testing only, thus if you want to be a volunteer to test this new released Office 2010 you can download it in Microsoft Download Center and make a test or evaluation to assist Microsoft to design the best for Office before it is lifted up to be RTM next year.

The build number of this release is 14.0.4536.1000 and the newer one from the one I posted months ago in: Download Microsoft Office 2010 Beta 1

Here is the screenshot of Microsoft Office 2010 Beta:

The build number is the same with the version shared by MSDN and TechNet for their subscribers 3 days ago.
