It’s a pain to download gigs of different Windows 8 edition ISO files, right? But when you will finish reading this article, you’ll be happy to know that you can unlock all the editions of Windows 8 from one ISO.

Actually Windows 8 ISO image contains all editions and Windows 8 Product Key defines which edition to be installed. Though the selection screen is locked by default but there is a way to unlock it. In this blog post, I will show you step by step process of unlocking all the edition of Windows 8 from a single ISO.

Windows 8 ISO image contains all editions (Core and Pro) but Windows 8 Setup doesn’t prompt or ask for user selection of which edition of the operating system they want to install. Instead Windows 8 ISO DVD installs the product key specific edition automatically.

After doing some R&D, I have figured out ISOs configuration and cracked it to opt for user direction to Windows 8 editions during installation. It is just like I unlocked Windows 7 ISO but the process is slightly different for Windows 8 Setup.


Note: The following method is legal, and doesn’t require a lot of technical expertise.


  • Windows 8 ISO from MSDN / TechNet sites
  • WinRAR / WinZip or other ISO extracting tool
  • Windows ADK (Windows Assessment and Deployment Kit)

How To:

  1. Download Windows 8 ISO from MSDN or TechNet sites (both are serving same ISO images)
  2. Use WinRAR / WinZip to extract the image; For instance I extracted image within C:\DVD_Data
  3. Open Notepad to create a file with following content and save as ei.cfg in Sources folder.

  5. Now create the bootable ISO or USB stick and burn your unlocked Windows 8 disc containing both Core and Pro editions.

    I want to create all ver 8.1 dvd/usb, but simply copy ei.cfg as 8 to 8.1 iso should not work. Any idea? Is only one change after create ei.cfg in 8.1. Installer can’t ask for the serial number at the begining of installation.

    Tried several times with Technet Enterprise ISO, but no luck.
    Checked /sources/ei.cfg inside ISO, and it’s right.

      Enterprise ISO contains a single edition only. therefore you need either Core or Pro ISO to unlock all.
