No doubt! Office 2010 Suite and Windows 7 are the best products ever and Microsoft is preparing the first Service Pack for both Office 2010 and Windows 7. Yesterday Office 2010 SP1 Beta made available to selected pool of testers via Microsoft Connect.
The Beta build number is 14.0.6011.1000 and weighs in at 294 MB (x86 version) and 361MB (x64 version). Like Windows 7 SP1, Office 2010 SP1 is mainly focused on security and stability but there is no official announcement and no extra information is available at the moment.
A nasty rumor in wild that this release has already leaked and available on torrents. It is recommended to avoid such leaked builds, it may contain virus and compromise Windows security and stability.
