The first omnibus update and patch package for Office 2010 32-bit and 64-bit. There are not many changes introduced with Service Pack 1 and these are rather cosmetic corrections, especially if we look at it from the point of view of the home user. However, we recommend that you install the add-on for everyone, as it includes a number of security patches.

Advanced users and companies will find in SP1 patches in the usability of the presenter view in PowerPoint, in cooperation with Project Server and SharePoint Server and in the backup of the latter. Search Server gained the ability to index PPSX files (saved slideshows), while in Visio there were fixed problems with scaling when exporting to SVG format. In Outlook Web Application, Exchange Online has introduced attachment preview.
