I think most by now understand what a pain in the ass XP’s WGA program is, but according to Softpedia, it’s not so bad when compared to Windows Vista. They mention that there are twenty different features and services being used with the sole purpose of reporting information straight back to Microsoft. This is not a secret though. Microsoft well documents all the ‘tracking’ techniques. Should you be worried? Who knows, but it’s unsettling regardless.
The Redmond company emphasized numerous times the fact that all information collected is not used to identify or contact users. But could it? Oh yes! All you have to know is that Microsoft could come knocking on your door as soon as you boot Windows Vista for the first time if you consider the system’s computer information harvested.
