After you run a windows update you may notice a notification that your “copy of office is not genuine". Then you will start to see a count down that “In X day(s), Office applications will be marked as not genuine.” Why is this happening? Microsoft, in there efforts to reduce software piracy, uses an update to prevent their software from being pirated. This mainly pertains to their Office suite products and operating systems. However, many complaints have been filed that people who bought legal licenses of office are generating this error.
Microsoft’s statement on false positives:
“While a false positive is possible, it is extremely rare. Across over 200 million WGA validations, we have identified only a handful of false positives. Almost all of these were due to data entry errors that were quickly corrected and only occurred for a short period of time.”
Microsoft’s general fix for these errors? Well, that’s where it gets tedious. If your copy is absolutely yours and you receive this error they tell you to contact your reseller or call Microsoft to hash out the problem. Isn’t there a quicker way?!
Sure there is! All you have to do is delete one file. Sounds pretty easy right? It is.
1) Close out any Microsoft Office applications
2) Navigate to C:\windows\system32
a) For 64 bit systems C:\windows\syswow64
3) Delete OGAAddin.dll
a) You can rename it if you like. Ex. OGAAddin.dll.old
4) Restart the Microsoft Application and the notification is gone!
Now if you do not like to delete system files and want to try and see why your products are coming up as not genuine, use the Genuine Diagnostic Site and Diagnostic Tool. The diagnostic site will help you troubleshoot your genuine notification and give suggestions on how to resolve the issue.

: I do not support any software piracy. This is a temporary workaround for people with legal licenses. In no way should you use this if you knowingly illegally own Microsoft software.
