How to Remove, Uninstall or Disable OGA (Office Genuine Advantage) (KB949810)

Recently (On April 15, 2008) Microsoft released an office update KB949810 know as OGA (Office Genuine Advantage) which once installed on your PC will refuse to uninstall.

If you review your updates history, you may find "Office Genuine Advantage Notifications (KB949810) en-us" under Office 2003 or Office 2007 because either your Automatic Updates were turned on or you allowed it to download.

This update does not show under "Control Panel", "Add Remove Programs" list even if you have tick "Show Updates" checkbox.

While non-genuine Microsoft products will face problems, it has also caused many issues for official license users of Office products.
Microsoft says that this was a "voluntary Microsoft update" but you have no control to uninstall once it is installed.


So, If you are experiencing a popup stating "You may be a victim of software counterfeiting."
You may be being a victim of the false positives the tool can throw up!

Of course, if you're running a pirate copy of Office then you just got caught out.

Here are two options that you can use/try.

Option One:
Download and run this program:

Option Two:
From the Run... option on your Start Menu, copy and paste the following line of text, to uninstall it from the registry.

MsiExec.exe /uninstall {B148AB4B-C8FA-474B-B981-F2943C5B5BCD}

You will be prompted if you are sure you want to uninstall. Click ‘Yes’
