Windows 7 Pro OA: Where to Find and Verify the Official ISO File



Windows7prooax1553895download: How to Get and Install Windows 7 Pro OA on Your PC




If you have a PC that came with Windows 7 Pro OA (Original Equipment Manufacturer Activation) preinstalled, you might need to download and install the original operating system in case of a disk damage, a system crash, or a format. However, finding the official ISO file for Windows 7 Pro OA can be tricky, as the links that contain the windows 7 64 bit ISO are no longer valid to download from Microsoft's website. So, where and how can you download the original operating system? Here are some steps to help you out:

Step 1: Find Your Product Key




The first thing you need to do is to find your product key, which is a 25-digit code that activates your Windows 7 Pro OA. You can find it on a sticker on your PC or on a certificate of authenticity that came with your PC. If you can't find it, you can use a program like ProduKey or Magical Jelly Bean Keyfinder to retrieve it from your registry.


Step 2: Download the Windows 7 Ultimate ISO File




The next thing you need to do is to download the Windows 7 Ultimate ISO file, which contains all the editions of Windows 7, including Windows 7 Pro OA. You can download it from this link: http://msft.digitalrivercontent.net/win/X17-59465.iso (for 64-bit) or http://msft.digitalrivercontent.net/win/X17-59463.iso (for 32-bit). Note that these links are official and legal, as they are hosted by Microsoft's partner Digital River.


Step 3: Verify the ISO File




After downloading the ISO file, you need to verify that it is not corrupt by validating its SHA1 hash value. A SHA1 hash value is a string of numbers and letters that identifies the file. You can use a utility like HashCalc or WinMD5 to check the file and compare its SHA1 value with the one listed below:


  • Windows 7 Ultimate 64-bit: 36ae90defbad9d9539e649b193ae573b77a71c83



  • Windows 7 Ultimate 32-bit: 65fce0f445d9bf7e78e43f17e441e08c63722657



If the values match, then the ISO file is valid. If they don't match, then the ISO file is corrupt and you need to download it again.


Step 4: Remove the ei.cfg File




The next thing you need to do is to remove the ei.cfg file from the ISO file, which is a configuration file that determines which edition of Windows 7 will be installed. By removing this file, you will be able to choose Windows 7 Pro OA during installation. You can use a utility like eicfg_removal_utility or UltraISO to remove this file.


Step 5: Create a Bootable USB or DVD




The final thing you need to do is to create a bootable USB or DVD from the ISO file, which you can use to install Windows 7 Pro OA on your PC. You can use a utility like Rufus or Windows USB/DVD Download Tool to create a bootable USB or DVD.


Step 6: Install Windows 7 Pro OA




Now you are ready to install Windows 7 Pro OA on your PC. Just insert your bootable USB or DVD into your PC and restart it. Then follow the instructions on the screen and choose Windows 7 Pro OA as your edition. Enter your product key when prompted and complete the installation process.


Conclusion




Windows7prooax1553895download is not a difficult task if you follow these steps carefully. You just need to find your product key, download the Windows 7 Ultimate ISO file, verify it, remove the ei.cfg file, create a bootable USB or DVD, and install Windows 7 Pro OA on your PC. This way, you can enjoy the original operating system that came with your PC.
