Office Genuine Advantage (OGA) is a program by Microsoft similar to Windows Genuine Advantage (WGA) which requires users of the Microsoft Office software to validate their copy of Microsoft Office to download non-critical updates and other downloads such as addons, samples etc. This is different from Product activation in that activation is required to use the software and is enforced at the software level, whereas validation permits users to download files and updates from the Microsoft web site and is Internet-based. Validation rejects those product keys that have either been leaked widely or those which have been key-generated to pass through activation but not validation. Office Genuine Advantage covers Office XP, Office 2003 and the 2007 Microsoft Office System.

As of January 30, 2007, users of Office Update are required to validate the legitimacy of their Office software in order to download files and updates.^[1]

On April 15, 2008, Microsoft released Office Genuine Advantage Notifications to Windows Server Update Services as KB949810.^[2] The package is shown as "Needed" for client computers with Microsoft Office XP, 2003, or 2007 installed and is not removable after installation.^{[citation needed]} However, the notifications can be avoided by renaming/deleting three (or only two) files (OGAAddin.dll, OGACheckControl.dll and OGAEXEC.exe) in directory C:\WINDOWS\system32. The file OGAAddin.dll can be left, as it alone doesn't cause the notifications.^{[citation needed]}
