Why Remove Microsoft OGA?

Before discussing how to remove Microsoft Office Genuine Advantage tool, let us understand the tool, its pros, and cons. Windows Update installs Microsoft Office Genuine Advantage (OGA) as soon as your computer gains access to the site, after installation of Microsoft Office XP or later versions. The main role of the tool is to check the genuineness of the Microsoft Office installed on any computer. Though it does not harm anything, people wish to remove Microsoft Office Genuine Advantage as it presents false alerts from time to time.

Microsoft introduced Office Genuine Advantage tool to counter the usage of pirated versions of the Office software. However, the tool often creates hurdles whenever users open the software or prevents installation of Office Updates. This is because it cannot identify the Office software as genuine. If it finds the copy of Office as pirated while connecting to Windows Update site, it gives out a message saying, “This copy of Microsoft Office is not genuine.” It may also display the message in the System Tray whenever you start any Office application. Such messages are annoying, especially if you spent money on acquiring the MS Office software.

To make sure that users cannot remove Microsoft Office Genuine Advantage tool, Microsoft made sure that it is not present in the Add/Remove programs under Control Panel.

This option offers you a list of updates that you can install. You can always uncheck Office Genuine Advantage before installing Windows Updates. Alternatively, you can disable the Windows Automatic Updates completely and select Custom Install when you visit Microsoft Update site. If you disable Windows Updates, Windows Security Center will prompt you about Windows Updates every time you log in. This video shows you how to disable Windows Security Center notifications.
