RemoveWGA enables you to remove the Microsoft 'Windows Genuine Advantage Notifications' tool, which is calling home and connect to Microsoft servers every time you boot (pilot version), or every two weeks (current release).
Once the WGA Notification tool has checked your OS and has confirmed you had a legit copy, there is no decent point or reason to check it again and again every boot. Moreover, connecting to Microsoft brings security issue for corporate networks, and privacy issues for everyone. It is also unclear which information are transmitted (Microsoft published an official answer, but an individual study brought some questions). All of that, along the fact that Microsoft used deceptive ways to make you install this tool (it was told you it was an urgent security update, whereas it is a new installation giving you no extra security) might make one to call this tool a spyware.
Also, Windows Genuine Advantage Notifications is different than Windows Genuine Advantage Validation. RemoveWGA only remove the notification part, phoning home, and does not touch the Validation part. The Validation part is mandatory for some not critical downloads from Microsoft, but the Notification part is not mandatory at all, and you are able to install all of the security updates without installing this one.
I AM SURE YOU ALL WILL BE HAPPY AFTER THIS AND LIKED MY SUGGESTIONS TOO
