Traditionally, Office Service Pack patches cannot be uninstalled without completely uninstalling the Office product. But with the release of Office 2010, service packs can now be uninstalled via the Control Panel.

Microsoft has now released the Office 2010 SP Uninstall Tool for Microsoft Office 2010 Client Applications. This tool is contained in a package called Office2010SPUninstall.exe which is a self-extracting .exe file. The tool itself is a single file called OARPMan.exe. There is no installation for the tool OARPMan.exe.

Administrators or advanced users can use this command line tool to uninstall client patches included in Microsoft Office 2010 Service Packs.

This uninstall tool does the following:

• Uninstall client updates only, and not server updates.
• Uninstall Office 2010 Service Pack only.
