What is WGA Notifications?

Windows Genuine Advantage Notifications is a program that helps Microsoft fight software piracy and helps you validate that the copy of Microsoft Windows XP installed on your computer is genuine and properly licensed.

By confirming that your copy of Windows XP is genuine, you can take advantage of all the capabilities, support, and continuous improvements—as well as the peace of mind—that come with using genuine Windows. If your copy is not genuine, WGA Notifications will provide periodic reminders to help you take the appropriate action. It's part of Microsoft's commitment to fight software counterfeiting and help you avoid problems before they happen.
