A few Microsoft Office 2010 users have complained about Service Pack 1 (SP1). When they installed SP1 for Office 2010, they started receiving various error message while working in Office applications.
The only solution to fix their problem was to completely uninstall SP1 from their system. But sometimes users are not able to uninstall it from Programs & Features in Control Panel.
To fix this problem and to make people life easier, Microsoft has released an official uninstall tool for Office 2010.
"Microsoft Service Pack Uninstall Tool for Microsoft Office 2010" is a free tool which helps you in uninstalling SP1 for Office 2010. Its a command line tool which will assist with uninstalling client patches installed by Office 2010 service packs.
The Uninstall Tool enables you to uninstall the service pack without having to reinstall the complete Office 2010 product.
The Office 2010 SP Uninstall Tool is contained in a package called Office2010SPUninstall.exe which is a self-extracting executable file. The tool itself is a single file called OARPMan.exe. There is no installation for the tool.
Note that you must use a subfolder such as C:\subdir to expand the tool. You cannot expand the tool into the root directory of the hard drive (for example, C:\).
Once the tool has been extracted to a folder on the computer, it may be run from a command line. For information on the workflow, refer to the readme.txt file, which should be extracted to the same location as the tool.
It can be used in Windows 7, Vista SP1, XP SP3, Server 2003 SP2 and Server 2008.
This download is only available in English, however it will work with any language version of the service pack.
