So I got this lenovo computer which had no HDD in it. It still had the COA sticker on the side which stated that it was windows 7 pro lenovo. I put a small 80gb drive in it and grabbed my alienware disc that has windows 7 home premium on it. It installed without a hitch. However, I cannot activate this computer as it originally had 7 pro on it. So I did the anytime upgrade and used the key on the sticker. It took it . Now to activate. So I click on activate online only to find out it failed and needed to use the phone service to do so. I ended up using the smartphone activation choice and lo and behold, activation is successful. I now have a LEGAL copy of windows 7 pro on this computer. What's wierd is this windows 7 pro has all the dell alienware stuff still on it. I'll need to edit the registry to remove the logos and support information from the system properties screen.
