Microsoft Office 2010 beta is now available for MSDN and TechNet subscribers. Microsoft is expected to open up the beta, so that anyone who’d like to try it can download it possibly by the end of this week. Office 2010 beta is available for 32 and 64 bit processors but Office 2010 beta web app is only available for 64 bit computers and there is no information available on MSDN or TechNet when it would be available for 32 bit computers.
The most significant change in this Beta Build from the Technical Preview is the new installation procedure for test versions of Office 2010 SKUs, Upload Center, modified version of Backstage view and new refreshed icons for all Office products.
Microsoft has set up a public download page for Office 2010 beta. This download page lists all versions of Office 2010 will be available for download including Office Home and Business 2010; Office Professional 2010 and Office Professional Plus 2010.
