Hey. Can someone tell me what KB905474 actually does if you install it? I still believe my Windows version is genuine. I already have installed the nagware genuine advantage update but automatic updates is telling me to now install Windows Genuine Advantage Notification (KB905474)? Is this different from the previous update which allows windows to nag me to get a valid copy of windows? In a nutshell, what does installing Windows Genuine Advantage Notification (KB905474) do to my PC? Many many thanks.
