The Active X control checks Windows 2000 Professional licenses as well.
WGA also advertises the latest service pack, Service Pack 3, for Windows XP, which requires manual intervention to disable.
However, unlike previous releases, it started being only automatically delivered to Windows machines using four widely distributed product keys.
The latest update (version 1.9.0040.0) was released on March 24, 2009.
It is still possible to opt out of receiving this update using the "do not show" option at the Windows Update site (Windows XP), and the "Hide" option in the right-click menu of Windows Update in Control Panel (Windows Vista/7/8).
In addition to these notifications, Windows Genuine Advantage will also notify users with the message "This version of Windows XP is no longer secure" if users on an XP Operating System are not using Service Pack 3, and it will provide a link to help users to update their systems to the new service pack.
The latest versions do not roll out worldwide at the same time: the dates given are the earliest dates on which the versions appeared, so the actual version being offered in some places will be an earlier version than the latest release.It includes the following steps: The Active X control is downloaded on the first validation and when a new version is available, but the validation itself can be performed any time the user connects to a Microsoft Website to update.On Windows Vista without service packs, WGA validation failure has a greater impact.This behavior however has been removed in Service Pack 1 of Windows Vista in favor of prominent notices on systems believed unlicensed.When a user installs Windows Genuine Advantage, an Internet Explorer add-on is installed labeled "Windows Genuine Advantage".In early releases the tool could be readily disabled with the IE Add-on Management feature.
