We are pleased to announce the release of an update for the issue described in KB2612800 (Office 2010 SP1 installs SharePoint Workspace). This update is available on the Microsoft Download Center, start with the KB link to find the correct version.
This update is designed to correct an issue with SharePoint Workspace 2010, where components are installed during the Office 2010 SP1 update even if they were explicitly not included during the Office Professional Plus original installation. In certain situations, Microsoft Office Groove 2007 is upgraded to SharePoint Workspace 2010 when you install Office SP1.

This is a preventive fix that needs to be applied prior to the installation of SP1 to prevent the SharePoint Workspace (SPW) feature from being faulted in by SP1 or a later update. (If you already have installed SP1, please check the steps described in KB2612800)

<p>Hey Office SE team, I am getting updates for Outlook Social Connector once in a while and I download the installer and keep it. So what I would like to know is are the updates cumulative so I can delete all the older installers and keep only the latest update for OSC?</p>
