I have a Samsung N130 which came with Windows Starter. Since I had a OEM copy of Win 7 Ultimate, I formatted and installed that. Since installing, it keeps saying my copy isn't genuine (before I even connect to a network). Funny thing is this copy worked on my laptop, my pc, friends pc (x2) without any problems, they all show up as genuine. Any ideas why it doesn't work on this 1 netbook? Thanks.
