Microsoft has released Office 2010 SP1 (Service Pack 1) for all existing users of Microsoft Office 2010. The SP1 package is available for download as updates for both the 32-bit and 64-bit editions of Office 2010.
Office 2010 SP1 package bundles all previously released updates and also introduces new security, performance and stability updates. It also includes a number of fixes for almost all Office 2010 applications including Excel 2010, PowerPoint 2010, Word 2010, Outlook, OneNote and others. Like windows 7 SP1, the focus of this package seems to be more on bug fixes and performance improvements than introducing any new features. However, office 2010 already had several useful features to significantly boost your productivity at work.
