Uninstall Office Genuine Advantage Notifications Notifier (KB949810) with OGA Uninstaller
Office Genuine Advantage (OGA) is another initiative by Microsoft to stem the piracy and counterfeit copy of Microsoft Office business producitivity suite and applications. Since April 15, 2008, Office Genuine Advantage (OGA) Notifications was pushed to client computers installed with Microsoft Office XP, Office 2003 or Office 2007 as “Important” or “Needed” update, and is not removable or uninstallable after installed.
After installed, OGA validation component will perform a check on install Office software, and OGA Notifications notifier component will display various “This copy of Microsoft Office is not genuine” message if the Office software is determined as not genuine or not legitimate.
Although officially Microsoft prevents and disallows end-users from removing OGA Notifications (KB949810), there are several workarounds or hacks to remove Office Genuine Advantage Notifications. In fact, as it’s a MSI (Windows Installer) package which installed the OGA, the KB949810 OGA update can be removed and completely uninstalled properly and completely by using MSI uninstall string.

Jeff,
You wil need to manually do the steps above because RemoveOGA.bat will not work on vista due to security prompts.
I did this manually on vista and it worked.
November 9th, 2009 02:33
None of these worked for me, nor any of the unofficial workarounds. I am using Vista. I literally tried every single one. There is not even an .msi file IN my Downloads folder (as described above).

Its actually much simpler if you have retrieve the .msi from “C:\Windows\SoftwareDistribution\Download”
Then all you do is right click OGANotifier.msi and select ‘Uninstall’ from the context menu
You can also unhide it in Add/Rem Programs by deleting the SystemComponent subkey from the uninstall reg entries
