I bought a used Dell E6400 laptop which has a working copy of windows 7 enterprise. Not sure if it is the OEM copy or not. I want to completely reinstall windows fresh just to make sure there are no viruses or malware from the previous owner, however I'm a little bit worried about if i have all the necessary keys to get it up and running again. I do have a good windows install CD I got from these forums before. I ran SLIC Toolkit and it says there is no slic table found. I did copy the product key, however Slic toolkit said no certificate found. So I ran belark advisor and was able to find the product key and certificate. Should these 2 items be enough to reinstall the same version of windows, and get it registered as a legit copy, even though I don't know if there is a good slic table or not?
