Users who have installed pirated copied of Microsoft Office or using MS Office productivity suite along with MS Office 2007 blue edition, will now face Office Genuine Advantage notifications (OGA). All MS Office editions are getting updated with a security patch called KB949810, which will cause invalidating your MS office product key activation and starts showing a genuine notification like WGA (Windows Genuine Advantage) notification.

All MS Office suits are automatically getting KB949810 updates via MS Office auto update feature. Once it gets installed on your computer it checks for the product key number which you used to validate your copy and uses it’s database to check it’s genuineness. If it finds your product key number blacklisted, it will automatically invalidate your copy and starts showing the boring OGA notification.

The only way to hide, remove or block OGA notification is to disable automatic updates for MS Office so that KB949810 security update does not get installed. KB949810 update installs the following files in your system :

OGAAddin.dll
OGACheckControl.dll
OGAVerify.exe
WGATray.exe

You will see a notification like the following once all above files gets installed :

This copy of Microsoft Office is not genuine.

Please excuse this interruption. This copy of Microsoft Office did not pass validation. Click Learn More for details and for help identifying the best way to get genuine Microsoft Office.

Just after few hours of this security update, rumors are saying that Office Genuine Advantage Notifications crack or OGA crack has been released to block or remove OGA notifications. However, personally I’m yet to find the accuracy of this news. Whatever the case might be, Microsoft will move a step forward in this case also, like it did when WGA cracks were released.
