Official Ways to Disable or Manually Uninstall the Microsoft Windows Genuine Advantage Notifications from Microsoft

Microsoft has released step-by-step removal instructions to disable or manually uninstall pilot or pre-release version of Microsoft Windows Genuine Advantage (WGA) Notifications (KB905474) which is versions that range from 1.5.0527.0 to 1.5.0532.2, although the instructions can also be used to uninstall the updated release and general release of the anti-piracy tool, but it will not be supported. Instead, Microsoft recommends to install general release of WGA Notifications (1.5.0540.0) to replace and uninstall the pre-release version during the pilot program.
