Hi, As far as I know, there are no lists of hash values for Windows installation media. These values do not match the ones I found in my technet subscription downloads; but these are not OEM.. which brings me to another point: an OEM edition is usually build by the OEM, which can modify the image to a large extent. Things like unattended install scripts, logo's, backgrounds, prestaged software and drivers,... it all will modify the hash values like SHA-1, md5 and CRC. In case of doubt, you should really contact the OEM (the manufacturer of your computer). He will be able to tell whether the image is genuine. I feel obliged to advise you not to download windows installation media from untrusted sources (newsgroups, warez sites,...) but instead contacting your computer manufacturer or Microsoft for ordering replacement media. You will, of course, need a valid license key to install and activate your fresh copy of Windows 7 Ultimate! MCP/MCSA/MCTS/MCITP
