Win7 Certificate of Authenticity

[Mattus]

Hi all, quick question about Windows licensing.

I'm selling a retail copy of Windows 7 on an auction site. A potential buyer wants a picture of the Certificate of Authenticity which is on the top of the box.

Is it safe to give him this, or is there any way a product key can be deduced from the CoA? I highly doubt MS would be that silly, but just wanted to make sure.

Thanks,
Matt

sounds like he's just trying it on, get him a random one off google and say it looks just the same
