Windows 7 has been playing up the last few days and now its getting even worse. Started coming up saying I need to verify my product key and my wallpaper has gone black on the desktop and says ''windows 7 is not genuine''. Also states I must make windows genuine or else it wont work in 30 days time.
I have tried to put in the product key on the bottom of the laptop but it says its wrong... Anyone got any clues?
