I bought a Lenovo x200 for a throw away computer to use with Ubuntu, and after messing around with putting in a SSD I noticed there were two Win 7 COA stickers. The first is a genuine COA, Win 7 Pro, Lenovo Singapore. The second is a brown Win 7 Pro for Refurb PCs, says OEM Software. There is no COA number, just a barcode with a short number, and some xxx-xxxxx number, both are similar to the Genuine COA sticker. I also have a Win 7 Pro 64 bit Refurb disc that came with the computer. Everything looks legit. I did some google-fu, but my question is can this item be used on a completely different random computer, and/or multiple times if I wanted to? I read something about the key being tied to the disc, or the key to the computer, etc., but no one asking my specific question. Also, if I go to a flea market and find a Win 7 COA sticker and buy it, is it a universal key in the sense that I could use it on a computer, or in Parallels for a VM/Bootcamp? Edit: Just noticed that the xxx-xxxxx keys on the stickers are not the same as the key printed on the holographic portion of the install DVD.
