One of my friends has illegal windows XP. He asks me how to does his copy genuine. How I can do this? Does my friend need to buy new genuine windows? Is there another way to in spite of he doesn't buy new windows?
In order to resolve your friend's non-genuine licensing issue, have your friend visit: www.microsoft.com/genuine and click on "Validate Windows". When validation fails, your friend will see a button to click on which will provide information on how to acquire a WGA Kit.
