After installing Office Genuine Advantage (OGA) Notifications (KB949810) from Windows Update, OGA Validation will perform genuine test on installed Microsoft Office XP, Office 2003, Office 2007 and Office 2010 software. If Office product is validated as not genuine, “This copy of Microsoft Office is not genuine” notification message will be displayed on notification area (system tray), at splash screen during Office program (i.e. Word, Excel, PowerPoint, Outlook) startup, and at Office’s toolbar or ribbon with extra “Get Genuine Office” tab or element.

KB949810 OGA Notifications update is designed so that end-user cannot uninstall or removed the update using “Add and Remove Programs” or “Program and Features” in the Control Panel, in a bid to encourage end-users to buy genuine Microsoft products. But, if you’re a legit Office users, and the OGA validation has returned false-positive result, use the one of the following hacks to disable and remove Microsoft Office not genuine notification messages displayed by OGA Notifications.

Note: Hack below simply remove and disable OGA Notifications so that no notification message about Office not genuine is not displayed, and works on most versions of OGA Notifications. It doesn’t crack or patch OGA Validation component, OGACheckControl.dll, which does the validation process to determine if the Office product is genuine or not.

Hack 1: Disable OGAAddin.dll from Loading with Office Applications

OGAAddin.dll (and OGAVerify.exe) is a few files that been installed by OGA Notifications. OGAAddin.dll allowed OGA Notifications to install as an add-in to applications in Office productivity suites to display not genuine reminder message to illegitimate and illegal copy of Office. By stopping the OGAAddin load behavior and preventing OGAAddin.dll from loading, the Office Genuine Advantage Notifications message can be suppressed.

  1. Run Registry Editor (RegEdit.exe).
  2. Press Ctrl-F to open search box, and search for OGAAddin.connect registry key.
  3. In the right pane, right click on Load Behavior and select Modify.
  4. Change the value data from 3 to 0.
  5. Repeat for each and every OGAAddin.connect found.

With this hack, Windows still treat OGA as installed, and will not prompt user to install again.

Hack 2: Disable and Remove OGAAddin from within Office Applications

  1. Run one of the Office app such as Word, Excel, PowerPoint, Outlook, Publisher and etc as administrator.

    Note: Open Windows Explorer, go to %SystemDrive%\Program Files\Microsoft Office\Office12 (may be different depends on version of Office installed and x64 OS uses Program Files (x86) folder), and right click on Office app executable, e.g. winword.exe, excel.exe, powerpnt.exe and etc to run as administrator.

  2. Go to Options (at the bottom of menu triggered by Office button) -> Add-Ins.
  3. Select COM Add-ins under Manage drop menu list, and click Go.

    Disable and Remove OGA Addin Add-In

  4. Disable or remoev the OGAAdmin.
  5. Repeat above steps for each and every Office applications installed.

Hack 3: Delete and Remove (Uninstall) Office Genuine Advantage Notifications Components

Although Microsoft does not allow OGA Notifications to be uninstall, but that does not mean that individual file components of OGA Notifications cannot be deleted, removed or uninstalled manually.

To disable OGA Notifications and uninstall KB949810, close and exit from all Office applications (including Outlook, Word, Excel, PowerPoint, OneNote, Publisher, Visio and etc.), and search for the following files in %SystemDrive%\Wndows\System32 folder and %SystemDrive%\Windows\SysWow64 folder (for 64-bit OS x64 only).


Delete the above files. It’s also possible rename the files so that system cannot find them.

Hack 4: Remove OGAAddin.connect Registry Key in System Registry

Pretty much similar to method 1 and 2, but it’s quicker and will complete remove trace of OGAAddin.connect from registry. Unlike hack 1, Windows Update may prompt you to install again.

  1. Run Registry Editor (RegEdit.exe).
  2. Go to each and every of the following registry keys, and any other which contains OGAAddin.connect registry value sub-key:


  3. Delete the OGAAddin.connect registry value.

Hack 5: Properly Uninstall KB949810 OGA Notification via OGANotifier.msi

Tip by AnonyMouse

Easy to uninstall. Just follow these steps:

  1. Go to C:\Windows\SoftwareDistribution\Download\8998da55d52b36c0e98ba016ddd50de0\ folder.

    Note: The directory may be different, so if not found search for

  2. Extract with WinRAR (or using the Expand command at command line) to get a file named OGANotifier.msi.
  3. Right click on OGANotifier.msi, and select Uninstall.
  4. Remember to block the update from been installed again in WU.

There is also an official Windows Installer method of uninstalling OGA, Belt-and-Braces approach submitted by one of the reader, shown below:

  1. Remove ‘Office/Windows Genuine Advantage’ from Office Programs:
    • Word / Excel / PowerPoint / Access

      Quick Access Toolbar – More Commands – Add Ins – Manage ‘Comm Add Ins’ – Go – Remove OGA Add In

    • Outlook / Visio

      Tools – Trust Centre – Add Ins – Manage ‘Comm Add Ins’ – Manage – Go – Remove OGA Add In

  2. Reboot into Windows ‘Safe Mode’
  3. Rename in \windows\system32 (by adding .bak to end of file)
    • LegitCheckControl.dll (create empty file)
    • OGAAddin.dll (create empty file)
    • OGACheckControl.dll (create empty file)
    • OGAExec.exe (create empty file)
    • WgaTray.exe (create empty file)
    • WgaLogon.dll (create empty file)
  4. Edit Registry (Navigate to WgaLogon folder)
    1. HKey Local Machine
    2. Software
    3. Microsoft
    4. Windows NT
    5. Current Version
    6. Winlogon
    7. Notify
    8. DELETE Wgalogon folder
  5. Disable OGALogon Task
    1. \Windows\tasks
    2. Select OGALogon and the ‘Properties’
    3. On Task Tab
    4. Disable as follows (Uncheck):
      • Run only if logged on
      • Enabled (Scheduled task runs at specified time)
    5. On Settings Tab
    6. Disable as follows (Check):

      Delete the task if it is not scheduled to run again

  6. Restart Windows Normally
  7. Block Programs in Firewall (Prevents running IF there is an automatic Update)
    • OGAExec.exe **create empty file (If not done in 3)
    • WgaTray.exe **create empty file (If not done in 3)

With any one of the hacks above, no more Office Genuine Advantage notification message will be displayed and showed on system, regardless of genuine status of the Office software, unless of course, end-user chooses to reinstall KB949810.

  • sammy

    very helpful tips. thanks for sharing.

  • Mexgeek

    I found an easy way. Go to my PC, windows, system 32 or system 64, find files that start with OGA, rename them. For example: OGAAddin.dll change to xOGAAddin.dll.

    Do the same for all three file that star with OGA.

    Restart computer. That's it!

    It appears instead of going through all the procedures in Hack#2 all you need to do is locate the OGA file:

    All the check marks were now removed from all the Office apps and stayed that way even after a reboot.

    Hack #2 does not work for me. I had found this example a long time ago for my xp version of Office. Now with Windows 7, Office has o be run in Admin mode to turn it off. However, the program doesn't work in admin, stating that "there was a problem sending the request to the program" this is only when opening an Office file outside of the program. I've tried running as admin whilst the program is running, but the banner comes up again after the computer turns off. Any ideas?

    You can also just delete the .dll file in the system32 folder. I know this sounds shady, but when the add-ins menu in office 2007 word told me where the .dll was, I just went and deleted it. No errors, no problems. That section of the ribbon is gone and everything's good. This would be a safer approach for people who don't like messing with their registry.

    @Dioxanne – REPLY 97

    Fantastic! Great tip it works!

    I was changing the registry values before going to task scheduler as Dioxanne indiacted and they kept automatically reverting after reboot.


    Following Dioxanne's tip…

    1. Look in Scheduled Tasks:

    – Start buttons / Programs / Accessories / System Tools / Scheduled Tasks

    2. Disable “OGALogon”:

    – Right click on OGALogon / Properties / Uncheck Enable Box

    …everything is fine and the registry values remain at zero, and I am not getting any annoying pop up windows messages anymore.

    One thing I would add though is that I am running Vista Basic and I am not sure if it is just my operating system or Microsoft being SNEAKY but I had to do this…

    1. Look in Scheduled Tasks:

    – Start buttons / Programs / Accessories / System Tools / Task Scheduler

    2. Click on Task Scheduler Library,navigate to Microsoft, and then to the Office Genuine Advantage Folder. NOTICE it seems empty, HOWEVER right click on it, go to view and SHOW HIDDEN TASKS! You will now be able to see OGAlogon, right click on this and choose disable. DONE! Sneaky microsoft trying to hide it!

    Then just follow these steps, they work perfectly;

    1. Run Registry Editor (RegEdit.exe).

    2. Go to each and every of the following registry keys, and any other which contains OGAAddin.connect registry value sub-key:





    3. Delete the OGAAddin.connect registry value.

    All the best everyone. 🙂

    I tried all hacks except for #5. With 1, 2 & 4 the add-on would re-appear after a reboot. Then I removed OGAAdin.dll, OGACheckControl.dll and OGAEXEC.exe (don't have a OGAVerify.exe) from system32 and it didn't come back after a reboot. So they're in the bin now and it's going to be emptied, and I am happy for now. Thanks.

    I followed Hack 2 told in here and it worked for me temporarily and I didn't follow any other hacks here so dunno if they work.

  • Hack 4 worked for me, I'm very happy! Thankyou! 🙂

  • Dioxanne

    I hope everyone here knows that MS watches and reads these workarounds – as I said before, the reason those hacks didn't work for me is because they changed stuff in a later update I am sure.

    So MS, here's the deal:

    If you change it again, I will buy a MAC, no longer support you by buying your software and just use Wordperfect instead (which I have anyway).

    As far as I am concerned, after that whole MS Millennium debacle (which just about gave me PTSD), MS should have given a FREE COPY OF XP to anyone that sent in a Millennium hologram CD!!!

    What a joke and they are doing the same thing with Vista = Win 7 but at least the manufactures will give you an upgrade coupon.

    Shame on you Microsoft.

  • Dioxanne

    I tried almost all of the above hacks and none worked – I think because MS changed something in the way OGA works, probably from a later update. I DID find another work around though and an even easier one:

    1. Look in Scheduled Tasks:

    – Start buttons / Programs / Accessories / System Tools / Scheduled Tasks

    2. Disable "OGALogon":

    – Right click on OGALogon / Properties / Uncheck Enable Box

    Hack #4:

    Quoted from above:

    Remove OGAAddin.connect Registry Key in System Registry

    Pretty much similar to method 1 and 2, but it’s quicker and will complete remove trace of OGAAddin.connect from registry. Unlike hack 1, Windows Update may prompt you to install again.

    1. Run Registry Editor (RegEdit.exe).

    2. Go to each and every of the following registry keys, and any other which contains OGAAddin.connect registry value sub-key:





    3. Delete the OGAAddin.connect registry value.

    BTW, I tried only doing Hack 4 WITHOUT disabling the OGALogon and at boot or Log on, the Registry values would reappear.

    I think because OGALogon "tells" your machine to check all values and make sure that the OGA is active.

    So far no prompt from MS update to reinstall because I think by disabling the scheduled task, it still thinks OGA is there and working.

    Hope that helps!

    Remove Office Genuine Advantage Reminder (hack 6?)

    It requires no file modification what so ever, only a small change to folder permissions.

    This version has been tested over Windows 7 Professional running Microsoft Office Enterprise 2007 SP2

    Step 1:

    Go in C:Usersyour usernameOffice Genuine AdvantageData and in the latter folder

    Set folder permissions to deny all for your username.

    [Of course, now you won't be able to store anything in this folder… that's quite sad.]

    Then, if you start any Office Product, the reminder won't show.

    Very easy to uninstall in Vista. Open the command prompt or simply type cmd.exe on start, the command prompt opens, type in cd C: to switch, then copy and paste "MsiExec.exe/X{B2544A03-10D0-4E5E-BA69-0362FFC20D18}" (without the quotes ""), and click enter. To paste click the icon on command prompt, edit, paste. Nice. —- Do you want to uninstall bla bla bla, Yes ofcourse, OK. Enjoy!!!

    I hid this update in Microsoft Update weeks back. I would check occasionally and it would be hidden as it should be. Now, it no longer shows up when I restore hidden updates and it is also not in the update history… where is it?

  • Westman

    On vista home premium, step 1, instead of the vaue 3 it was 1 and just changed the 1 value to 0 and it worked.

  • mystery11

    I tried hack 2 and it stopped the notification comming up.

    BUT, will it still mark my office as "not genuine" like it said it would do in x number of days?

  • jack holland

    Hack 1 worked for me fine – thank you

  • TJ

    I just used them all. Vista users don't have all files mentioned in nr. 5, also in the registry there are no folders mentioned in the explanation. Eventhough it worked nicely! Thanks very much for the information!

  • Hack 1 worked. I am no longer getting the annoying message that microsoft office is not genuine.

  • blucecloud

    Thanks! Hack 2 worked for me. ^^

  • Hack 3: There's no file called OGAVerify.exe in Vista system.

  • A. Naja Domingos

    Many thanks. Hack 3 was the only that worked for me. In addition, apart from OGAAddin.fll file, in my case I had no OGAVerify.exe in my laptop. Instead, I had to delete OGACheckcontrol and OGAExec files.

  • Thanks to Shaamaan for his/her input. I had tried hack #s 1, 2, and 4 with negative results. His suggestion worked for me. Thanks to everyone's inputs on this issue. A lot of excellent information.

  • Shaamaan

    Once again, the first hack does work, but requires an extra modification (on Vista / W7… PROBABLY won't work on XP).

    For each key that you modify (and change the 3 to a 0), in Regedit, click on Edit then on Permissions. In the top list select SYSTEM and in the bottom list check Deny for Full Control. Press OK, and you're done. That given key will never be changed by the system, ensuring the addin will never load.

    Do this for each registry entry for each MS Office product you have, and you will end up with a working Office, no nagging screens and you can safely use Automatic Updates.

  • oldbutwise

    Hi, I was able to perform a system restore because the update just installed itself yesterday.

    Is a system restore sufficient to remove the KB?

    Thanks very much!

  • Yiannis

    I have Windows XP Pro SP3, Office 2003.

    In hack 5 there is not the mentioned file C:WindowsSoftwareDistributionDownload8998da55d52b36c0e98ba016ddd50de0 and searching I can’t find it.

    Instead I found in C:WindowsInstaller folder a file name 2a974f2.msi,116kb saying “The installer database contains the logic and data requested to install OGANotifier 2.0.0048.0.

    Can I unistall this file in place of the mentioned ??????

  • crazyguy

    I tried method 5 but it didn't work.

    I have vista and office2003.

    I found the OGANotifier WinRAR file and extracted the OGANotifier.msi.However, when I right click there is no option for uninstalling rather there is a option for extracting.So I extracted it to the desk top and then uninstalled.Though there was a message that it has been unistalled, actually it has not.

    Please help guys.

    WHEN I AM CLICKING LERN MORE website is trying to install legitcheck.hta for validating . still i didnot install that file. Please help me how i will solve this problem? i am waiting for your answere

    thanking you


  • hate MS

    I know you people have no reason to believe me, but the command prompt crack does work. I am surprised no one has responded on forums or actually mentioned this anywhere else, but if you are having trouble using the other hacks (the registry value hack doesnt work in vista) and others, well this is a technique used to initialize the program and actually this simply removes the OGA install…I did it…it removed the OGA install and then i just hide that update

  • .bil

    the MsiExec.exe /X{B2544A03-10D0-4E5E-BA69-0362FFC20D18} works perfect under vista/office 2007 ent.

    the thing is that the reply buttons are not showing any more on the outlook 😐

  • Carl

    Thank you so much for your tips.

    I installed this update thinking my key would pass validation but it didn't.

    You have been very helpful for several years now.

    My Digital Life rocks !

  • Sidney

    Hack 4 worked !! Thank you so much.

  • Wyart

    Once again, I would like to emphasize that, though it might function in Windows XP, Method 1, .reg file or not, DOES NOT WORK with Windows Vista, given that the system somehow automatically rewrites the registry and replaces the key values from "0" back to "3".

    I would enormously appreciate it if someone would find a way to make it work in Vista as well.

  • anonymous3


    September 17th, 2009 01:14

    if you issue this from a RUN or CMD prompt it will force it to uninstall itself.

    MsiExec.exe /X{B2544A03-10D0-4E5E-BA69-0362FFC20D18}

    This is much safer."

    this guy is the best. everyone should do this.

    it is so much safer and about 10 times quicker! props to you man

    Your command worked perfectly! It could not get any easier than this! THX!!!!

  • ErrorHelp

    Method 1 works great! I like it the best because I can leave Office Genuine Advantage (KB949810) and dont have to worry about it reinstalling itself through Microsoft Update.

    I made a .reg file that makes outlook,word,excel, and powerpoint not load this problematic nag screen. This is the text for the reg file for Office 2007 Enterprise on Windows XP SP3:

    open notepad

    paste the following:

    Windows Registry Editor Version 5.00


    "FriendlyName"="Office Genuine Advantage Add-in"


    "Description"="Office Genuine Advantage Add-in"


    "FriendlyName"="Office Genuine Advantage Add-in"


    "Description"="Office Genuine Advantage Add-in"


    "FriendlyName"="Office Genuine Advantage Add-in"


    "Description"="Office Genuine Advantage Add-in"


    "FriendlyName"="Office Genuine Advantage Add-in"


    "Description"="Office Genuine Advantage Add-in"

    Then save it as OGAfix.reg

    Make sure it is a .reg file and not a .txt file. Google will show u how to make a .reg file.

    Run the .reg file and you should be good.

    If you want to do it manually:

    Open regedit

    Go to:



    Microsoft >


    Highlight that Office key and go to


    Find what: OGAAddin.Connect

    Look at: check Keys only

    Match whole string only: should be checked

    Find next

    Each key named OGAAddin.Connect will be in the Addins key for each office app. For each OGAAddin.Connect in the office key, change the value of the Dword LoadBehavior from 3 to 0 (thats a zero)

    Repeat for each OGAAddin.Connect key in the office key.


  • anonymous2

    if you issue this from a RUN or CMD prompt it will force it to uninstall itself.

    MsiExec.exe /X{B2544A03-10D0-4E5E-BA69-0362FFC20D18}

    This is much safer.

  • gio

  • jayne

    thanks! used hack 3 and it worked!

  • TY

    thanks 4 hack 5. worked a-okay

  • hackjob

    Hack 5 worked, but key is to unzip it into a folder outside Windows as mentioned by Friendly1. Would not unzip otherwise. We can't just stop auto updates of Office, right? We must stop all auto updates and manually avoid the noted file, correct?

  • inc

    Last method of uninstalling the update worked perfectly. Thank you very much.

  • Pingback: Remove OGA Office Not Genuine Notifications (KB949810) | incubus()

  • Friendly01

    Hack 1 did not work for me with Vista. I tried Wyart’s emule download but got a little concerned because AVG found Trojan’s in both exe files, might be false positives but why chance it. I did keep and install the hacked OGACHECKCONTROL.DLL from the emule download though as this was clean. Based on Wyart’s experience, this must be a hacked version of OGACHECKCONTROL.DLL, dated 8/12/09, if as he reports, the office passed validation. I just used Hack 5, but suggest you use a freeware program, ”IZArc”, that will open the cab file and most everything else. Just remember to open/extract it to a folder outside of Windows or you will get some error message. Once extracted, right click OGANotifier.msi, and select Uninstall. With this combination of hacks, I get no “not genuine” messages and no prompts to reinstall the KB949810 as it still shows as being installed. I did not change my Office Key, thinking if the hacked OGACHECKCONTROL.DLL does it’s thing, I am not sure it is necessary. I do not know if I will be able to get the Office updates as my copy is fully updated so I don’t know how to test this, mean while, everything seems to work fine and no nag screens.

  • dave

    @Wyart: Solution? No more auto-updates. You'll have to download them manually.

  • Wyart

    The damn warnings came back. I seem to have no ther choice but to uninstall KB949810 and hide it in the Windows Update, hoping that this will not keep me from other, effectively useful, updates. The registry hack sugested by Shaamaan sounds interesting, but a little too technical for my taste.

  • Shaamaan

    I've noticed on my system that after a reboot the registry values return to defaults (3). I managed to stop this by setting permissions for these keys and DENYING ALL access to SYSTEM.

    This is on a W7 system. If memory serves, there weren't any registry permissions back in XP, were there?

  • Wyart

    A full day has passed and no pop-up warnings so far. It seems that when KB949810 flags your Office as non-legitimate, it wants you to click on the "more information" button and have your installation verified (as in a process started by KB949810 itself, not a random navigation from your browser). Once it does that, and it is satisfied with the result, no more warnings.

    If the error does come back, I'll let you know.

  • Douglas Graciani

    For those haven't the required file and want to uninstall the OGA.

    Please, check this link –>… (712 KB).

    Must be the lastest version (Info provided by the MSI Installer inside de .CAB file–> This installer database contains the logic and data required to install OGA Notifier 2.0.0048.0).


  • Wyart

    Sadly, it seems I had spoken too soon. My bad validation was corrected (now I validate just fine) but the nag comes back the next day. I trued clicking the "see what you can do" (or whatever it is) button, which opens your browser on a validation page which my system passed. I'm waiting for tomorrow to see what happens.

    Pehaps this is a problem of some automatic scheduled task the patch imposes?

  • Fred

    This fix does not work.

    I changed the key and I still get nag and fails to validate.

  • flipper

    I still get the nag even after applying the patch from Wyart and going to MS to validate. I validated yesterday with no problem at the website but today I get the popup again. I reapplied the patch and again went to the MS site and it validated correctly. So it seems that patch does not work completly after a day or two.

  • Chi Chi

    I don't know what you're talking about.

  • Wyart

    All of the necessary files can be found in the link:


    Just type it in your browser address bar and it will start downloading the file (requires e-mule).

    The procedure is to first install the infamous KB949810 update (Office Genuine Advantage v2.0.48.0) and then patch it by means of overwriting your OGACHECKCONTROL.DLL, located in c:windowssystem32, with the adequately validated version. Then, not only will the nagging messages be gone, but you can visit the Microsoft Validation page and find that your version of MS Office 2007 is validated, thereby being elligible to receive critical, non-critical, and/or optional updates from Microsoft.

    If, by any chance, you install KB949810 and go to the Microsoft Validation page before installing the above patch, then your product will fail the Vidation and be flagged as non-genuine. Thus, in that case, the later application of the patch will not stop the warnings from popping up. However, even in this scenario you can still solve the problem by simply changing the Office Key and then checking again the Validation with Microsoft.

    The Office key may be changed by using the following procedure:

    1 – Close all Microsoft Office programs.

    2 – Run Regedit.

    3 – Locate and then click the following subkey: HKEY_LOCAL_MACHINE SoftwareMicrosoftOffice12.0Registration

    4 – Find another subkey that resembles the following:

    5 – Delete the following two registry entries by right clicking on the registry entry in the GUID subkey, click Delete, and then click Yes: DigitalProductID and ProductID.

    6 – Exit Regedit.

    7 – Open an Office application program, such as Microsoft Word, and see Office 2007 prompt you to enter a new 25-character product key.

    8 – Use the Office Keygen to generate a new key (click on the "search" button).

    9 – Copy and Paste in the new product key, and then click OK.

    Either way, the end result is KB949810 installed, NO nag screends or warnings, and a fully Validated MS Office 2007 that can receive future patches and upgrades from Microsoft (security or otherwise).

    Not bad, huh?

  • billy nomates

    cheers 1 worked a treat, was fed up trying to persuade tech support my version was genuine,

  • Wyart

    I changed the Outlook entry in my case (even though I dont use Outlook and even uninstalled the basic version that comes with Vista). The modified entries simply switch back from "0" to "3" the next day.

  • Rick

    I had the same problem with hack 1 as Wyart, until I realized I had Outlook still running. After closing that down, and modifying the registry keys again, hack 1 worked flawlessly. I no longer have the notifications. Thanks!

  • arg

    I just used hack 5. Will I not be able to receive office updates anymore??

  • Wyart

    Hack 1 does not work, which is a shame, for it is the only one that proposes to supply "the best of both worlds", i.e., leave the update as installed, allowing for future updates, but rendering it harmless. In my case, the entries simply return spontaneously. Maybe it is just incomplete, that is to say, there is some other registry key to edit to avoid the entires being written back to their original state?

    Hack 5 works flawlessly but, of course, it leaves you with a crippled, "updateability-challenged" Office.

    Any suggestions?

  • Raj

    Hack 1 Worked very well for me. Thanks. Great job.

    nothig will happend,
