No, it was not me who posted about used laptop. I also faced same issue as him so posted my issue in the thread he started. Two weeks back I bought a new desktop from a vendor who said he has installed genuine OEM license. Yeah, it looks like he has cheated me. Thanks for your response my2cents!
Thanks Mr. Showdown and my2cents! I have attached a scanned copy of the activation window. What is KMS licensing? My vendor said he has installed genuine OEM version of Windows 8 Pro. Have I been cheated?
