You bought a laptop with Windows 7 license (probably Home Premium or Professional). But the manufacturer did not provide you with the installation media (CD/DVD). Bummer. They did provide you with the recovery kit or recovery partition but you think that their installation has damn too many bloatware (yes brother! you are right, kudos !). You want to start anew with a fresh installation of Windows 7, SP1 all by yourself. Hold that thought….

  • You don’t have the Windows 7 <whatever version,build>SP1 DVD.
  • Since you already have the license, you don’t need to buy a new one. So, you just need to download the ISO file.
  • But where to download? (Stop scratching your head !) head out for a torrent site.
  • Then, you start nagging and wondering whether the ISO has been tampered by crackers / hackers or what not, waiting to exploit your computer to be their botnet minion. (Mind you, 99% of Windows 7 ISO that one downloads via torrent has been tampered with, which basically means that somebody has modified the original ISO and injected something (either a non-malicious software such as an unlocker, pdf reader,a new build OR an extremely malicious software such as a rootkit/trojan/etc. A big warning placard if you do use your computer for internet banking or often purchase items via credit or debit card).
  • So how to ensure that the ISO files have not been tampered with? Well, this is what you should do.

A few years back laptops usually surfaced with Windows 7 Home Premium x64 SP1.

  • You will find Windows 7 Home Premium x64 with SP1 in the ‘ISO NAME AND HASH KEY (RECORD) just below. From there,copy the file name,viz :
  • Search (Google) en_windows_7_home_premium_with_sp1_x64_dvd_u_676549.iso and download it. Hell yeah !! you found it at piratebay.
  • Download the torrent. {I believe that we are not breaking any cyber laws by downloading something that we have already paid for. We own the license after all 😉  }
  • Once the download is complete, you need to check whether the ISO is genuine or has been tampered with. Download MD5 / SHA1 Download Checker. [no sneakwares] Get it here from CNET.
  • Use MD5 / SHA1 Download checker and openen_windows_7_home_premium_with_sp1_x64_dvd_u_676549.iso. Get MD5 and SHA1 value.
  • Compare the MD5 and SHA1. Ideally, the one that is generated by the MD5 / SHA1 Download Checker should be identical with the record below. (Where did I get these? Refer to the ISO NAME AND HASH KEY (RECORD) Section.
  1. SHA1: 6C9058389C1E2E5122B7C933275F963EDF1C07B9 
  2. ISO/CRC: 4A182640
  • If they are identical, you are safe.

PS: Some tidbits for those who are feeling damn lazy…Scroll down to the end of this page. Mind you, please double check the hash. If you don’t trust the Hash record here, please check .You can use your Live / Hotmail / whatever account to check the hash key, the only complication being you cannot download a legal copy yourself from there assuming that you are not their ‘special’ subscriber .
