HI guys .. can you help me with my window. My window's edition is Window 8.1 Single Language. My laptop always shows that i need to activate the window and it will expire soon but i can't remember my product key and in the settings said under Activation Windows tab "the product key should be on the box that the windows DVD ... etc." and i don't have that DVD. I try some of the product key that i search from google but nothing works I'm so worried right now.. i need your help guys. Can i have a Product Key for free?
