How to Get Rid of Microsoft Office Genuine Advantage

Updated on May 16, 2013

This is a file that Microsoft may have installed on your computer during one of the Office upgrades that been downloaded on to your computer when you have Windows set to automatically install updates as they become available.

While Microsoft can only be applauded for trying to protect their business against fraudsters who use copied files and programs, this particular tool has caused many problems for people with genuine paid-for versions of Microsoft Office.

After the installation of OGA, as it is known (file No. KB949810), when you open any office application you will see a warning that your copy isn’t valid, and a count-down will commence for your product’s demise.

If you don’t have a genuine copy of Microsoft Office, you will have to buy one if you wish to continue using the program. That is only fair. You can click here, and this link will take you to Microsoft’s website where you can purchase a genuine copy.

Genuine Copy Microsoft Office

However, many people, myself included, have a genuine copy of MSO, and this is where you need to find a workaround so that you can continue using your genuine copy.

Do not download any files or programs from the internet that describes itself as a ‘fix’, unless you know the site that you are downloading from is 100% trustworthy. Many Warez sites will happily include a nasty little virus or Trojan horse in the .exe file which will ruin your computer, or worse still, steal your passwords and remove all monies from your bank account.

I just had to include this video. The guy communicates through Notepad to the viewer, and he really really needs the spell-checking functionality of Microsoft Word!


Fixing the problem yourself is relatively easy, though it helps if you have a little computer savvie, and are not afraid to use it.

Follow these steps if you have this problem with Microsoft Office XP, Office 2003, Office 2007 and Office 2010.


Start ->Run -> (type in) regedit.exe

Press Ctrl+F to open the search box, and look for file named OGAAddin.connect

In the right pane, click on Load Behaviour, and click Modify

Change the value data from 3 to 0

Press Ctrl again and repeat process for every instance of OGAAddin.connect found.


Renaming Files

Now, if, like me, you found that the value data was already set to 0, the other option is to do what I did, and rename every instance of the OGAAddin file. Call it OGAAddin42 or whatever, just rename it. By renaming it, windows can’t find it, or else it doesn’t recognise it and so ignores it.

Renaming any file will cause Windows to ignore it. This is especially useful to know if you have a virus and know the names of its files. This is how your virus removal software normally gets rid of harmful files. The useful thing about AV programs, is they know how to search for intruders, and recognise a rogue file. This is why it is so important to keep your anti-virus programs updated, as there are new malware files being written all the time. Your AV is instructed to seek them out and rename them to render them harmless.

Change Windows Update Settings

After you have got rid of the Windows Office Genuine Advantage notifications, you do not want a repeat of them, so change the settings for your Windows Update files, and make sure you do NOT re-download the file called KB949810.

Microsoft Office Genuine Advantage

Check the video here to see if your version of Microsoft Office is genuine or not. This is especially important to know if you are considering, or have bought, a second hand computer already loaded with Microsoft Office.

Have you had a problem with OGA when you have a genuine copy of Microsoft Office?

      I'm not sure Jan, hopefully someone else will know and comment here, but my suggestion would be to stick to your Office 2003 because IMO it is better software.

      I have a question related to this: I'm about to abandon my dying computer (which does have this annoying popup message about not being genuine) and start using my former assistant's newer computer. I need however to upgrade it from Office 2003 to 2007. Should I buy the full version (ouch! very costly for my little one-man company!) or can I buy an upgrade version? Will the upgrade version recognise that the original is a pirated copy? I want to be legit but I also don't want to spend more than necessary.

      ...and there's a workaround! They are not as clever as they think they are! lol

      But hey thanks for stopping by :)

      Oh and I've got a paid for version of Vista . It's awful! I really want to be on Win7 which by all accounts is the more stable system.

      There is. Just do a google search for it. I think the file you will be looking for is called WgaLogon.dll

      I've not had that message., but there is a workaround for everything.

      Microsoft has also incorporated genuine advantage into it's operating systems through updates. I first noticed when I lost my windows xp disc for my other computer and had to dig around until I found a very old xp disc I had from one of my first computers. Turns out the batch numbers did not match and I had to use a friends copy of xp which did not ask me for a product key. Not long after running the necessary updates a windows genuine advantage bubble appeared and stayed on the bottom right hand side of my screen as well as warning on start up that would prompt me to validate windows or buy a valid copy.

      Thank you for this article, if there is a work around for office it's likely there's one for XP too.
