On the bottom right hand corner of my computer it says windows 7 build 7601 this copy of windows is not genuine. How can i fix this? I bought the computer four years ago from lenovo, it was a new computer, not secondhand or anything and I have not played with any of the software. There is nothing illegal with it so please don't comment saying I pirated windows because you will not win a fight with IBM. I am hopping there is a setting i can change or something that will fix this problem. I have no illegal software on this computer so it is a problem with in the windows software.
