This is my story. I promised my younger sister that this time on her birthday i will gift her a genuine windows 7 ultimate.I have downloaded iso but don't have a retail product key.I know there are alternate methods for activation but i don't want to break my promise and cheat her by using those. All I'm asking is that if somebody can share a retail key that would do the needful. I'm a poor man and can't spent money on buying. Somebody please help me.
