The first public beta of Microsoft Office 2010 is now available as a free download on microsoft.com/office. You can either upgrade your current version of Microsoft Office to Office 2010 Beta or select the Customize option during installation and set your current version of Microsoft Office to coexist with Office 2010 Beta.
All products require online activation after installation. In case of Office 2010, you can enter the serial number inside Word 2010 and it will automatically activate all other Office applications. Project and Visio will require separate activation since they use a different set of keys.
The beta version of Office 2010 will expire in October 2010
