According to ibnlive.com started today (June 1st) Microsoft will be utilizing their Genuine Advantage check through the Automatic Update feature. Up until now, you have only been prompted for the Genuine Advantage check when visiting the Windows update site directly. (I can only assume the Genuine Advantage check is the method the article speaks of to verify if you have a licensed copy of windows.) Essentially, they say they will not be taking details like name/address, but they will nag you that you have a pirated copy of Windows and updates will not be available.
