Thanks Louis, these Amazon options are closer to what I was looking for. So I assume the first one on the list in the link you provided work for me? Or the one down the list just before the thumb drive? I am not sure what OEM means.
Earlier post with $139 options just didn't make sense to me which took me to used machines. TsVk, I wasn't referring necessarily to an original OEM sticker key, but rather an old XP or vista machine that somebody actually purchased a new win7 to upgrade, but have since moved on to newer computers. But the Amazon/Ebay solutions might work for me.
But this brings up a good point, If I have a machine, that I have purchased, built or upgraded and the machine dies (motherboard as example), I can't buy new components for home made computer and install the win7 I had bought?? That seems like a rip off.
