    Upgrading from evaluation version with old key


    Hi there,

    I recently went through a ton of issues with my lenovo y510p laptop and since it didn't come with a recovery disc, I was forced to reinstall windows 8 through a recovery disc on a usb stick. However, the only one I was able to get was an "evaluation version" of windows, so I've lost my original version of windows 8 after the reinstall. Is there any way to find my old key so that I can upgrade? I've tried a key finder, but it only finds the evaluation key.

    Would I have to contact Lenovo to see if they can give me my product key or is there an easier way?

    Thanks for the quick response!

    Unfortunately it came up with the same thing. It's almost as if the original product key simply disappeared when I used the evaluation recovery. I'm going to try contacting Lenovo to see if they are able to locate my product key for me.

    Thanks.

    Note you can't upgrade from Enterprise Evaluation anyway so you will need to get the software to re-install (when it will find the key in any case). A bit annoying in that way but the key may let you download it from MS rather than buying it from Lenovo.
