As was expected, Microsoft today on Day 2 of Professional Developers Conference (PDC09) has released Microsoft Office 2010 Beta to public via Microsoft Download Center. General public can now test and evaluate the latest version of Office 2010 to help make the product better before it hits RTM sometime next year. The Build number of Office 2010 Beta is 14.0.4536.1000 which is newer than the previously leaked build 14.0.4514.1009.
The Beta bits of Office 2010 Beta along with Office Web Applications are now up on MSDN and TechNet Plus. TechNet Plus and MSDN subscribers can now download and evaluate Office 2010 Beta before the official public availability on November 18th. 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. Office 2010 Beta is available in both 32 and 64-bit flavors.
