Rebooting
One thing to note here, Right now updater 5 is not supported any more, so even u just use autoupdate, by default Microsoft will install updater version 6, now which is under windows genuine advantage... !!!!
*update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us
So theoritically to install v6 updater, one must have genuine Windows, so before autoupdate checks the system for update, it would check whether its Genuine or not, so its kind of Force full installation of v6 updater there after the Genuine Advantage tool too..

once again, I dont have any offcial info on it yet
