We're getting new Lenovos at work with Win7 preloaded, and Win8 on DVDs. There is no key on a COA on the Lenovo for Win7. Since the SSDs they use are only 180GB, we typically yank it out and swap it with a 256/512GB per user needs. We then load Win8 from a clean USB stick which activates and life goes on.... ...except when the user needs Windows 7. My issue is, I don't know which version to install. I mean I know it's Pro, but I tried a clean full Win7 Pro install, and Jellybean Keyfinder got the installation key off the Win7 SSD, but when I try putting it in, it won't activate. I have a feeling the installation media they use is a special spin that I don't have, not a regular retail or MSDN image, but something specific to downgrade rights. I'm trying to avoid burning through our Win7 licenses unnecessarily, if I can figure out what type of image they use, I can just get it and activate it with the existing key.
