Hey everyone, so heres my situation. I am trying to format and reinstall windows on a clients computer, which normally is no big issue. This case is special though. Client has Windows 7 Installed, but the sticker on the case is for Windows Vista, ok no biggy. I call him up and ask him to bring his license in and this is what he brings me. https://windows7upgradeoption.com/Landing.aspx A black booklet that looks like the first of the two on this page. So I have never run across one of these things before so I check out the site thats on the booklet, which took me to that link I just sent. So my question is, what process from here do I have to go through to reinstall this guys windows 7? The license on this sticker is only 17 digits instead of the standard 25, so was this a code to gain access to the REAL code? or is this a special code used to install it? I assuming I cannot just pop in a windows 7 disk and use this code to install it like I normally would... Any guidance would be appreciated.
