Microsoft
intends to release Microsoft Office 2010 Technical Preview to invited
guests who register to sign up for Office 2010 CTP Program only by July
2009. Office 2010 was previously known by codename Office 14
(taken cue from its version), and wrongly assume to be Office 2009. The
setup installer of both 32bit (x86) and 64bit (x64) Office 2010
Technical Preview 1 (TP 1) has been leaked to BT network. The leaked
Office 2010 Technical Preview 1 has the version of 14.0.4006.1010, a
pre-trial version provided to premium Microsoft partners.

It’s unclear whether it is the leaked Office 2010 TP1 build will be the
version that is going to be released officially by Microsoft in July.
And it’s still unclear yet whether Microsoft will make available
publicly for Office 2010 Beta downloads, which is said to be will be
having 2 betas - Beta 1 in July 2009 and another Beta 2 in November
2009. The betas is said to be different from Technical Preview, where TP
is just meant as an engineering milestone for the development of Office
2010 and related products that leading to RTM that will reach in July
2009, according to Office 2010 IT Blog. Office 2010 is expected to RTM
and released as final product in March 2010, with the exception of
Exchange Server 2010, where Exchange Server 2010 beta already available
from official download links.

The setup installer of the leaked download will install Microsoft Office
Plus 2010 edition, with Access 2010, Excel 2010, InfoPath 2010, OneNote
2010, Outlook 2010, PowerPoint 2010, Publisher 2010, and Word 2010.
Project Professional 2010, SharePoint Designer 2010 and Visio
Professional 2010 are also included in the leaked RAR archive download.
Office 2010 supports Windows XP SP3, Windows Vista, and Windows 7.

Important note is that Office2010 TP 1 is still in early stage of
development, and may contain bugs, although most individual programs
such as Word 2010 and Excel 2010 are usable in everyday life. It’s also
interesting to know that Office 2007, the predecessor of Office 2010, is
version 12. Office 2010 will be version 14, skipping version 13, the
number that Microsoft assumes may be not so lucky.
