If you Want to Install Windows 8.1 Without Key I Mean Skipping the insert Product Key  option. Then You are in Right Place.

It’s often used in scenarios where you have multiple editions of Windows available within the same installation media, such as when you have access to different editions through a Volume Licensing agreement.

This approach can be helpful for IT professionals and system administrators who need to streamline the installation process and ensure consistency across deployments. However, it’s essential to ensure that you are in compliance with Microsoft’s licensing terms and agreements when using this method. Always consult Microsoft’s official documentation and licensing terms to make sure you’re using Windows in a legally compliant manner.

this technique is legitimate and is not considered hacking or illegal. It’s a method documented by Microsoft that’s often used by IT professionals and system administrators.

To summarize the steps:

  1. Prepare Installation Media: If you’re using a USB drive to install Windows 8.1, transfer the installation files to the USB drive. If you’re creating a DVD, use a utility like MagicISO to open the ISO image without altering its structure.
  2. Navigate to /sources Folder: Browse to the /sources folder within the Windows installation media.
  3. Modify or Create ei.cfg: Locate the ei.cfg file. If it doesn’t exist, you can create a new text document and rename it as ei.cfg.
  4. Edit ei.cfg: Open the ei.cfg file in a text editor like Notepad or Notepad++. Clear any existing content and paste the following content for the Professional edition:
    csharp
    [EditionID]
    Professional
    [Channel]
    Retail
    [VL]
    0

    This configuration specifies that you want to install the Professional edition using a retail channel and indicates that it’s not a Volume Licensing version.

  5. Save and Run Setup: Save the ei.cfg file. Run the Windows 8.1 setup again using the modified installation media. The setup process should not prompt you for a product key.

Again, it’s important to emphasize that this method is a legitimate customization option provided by Microsoft. However, ensure that you’re in compliance with Microsoft’s licensing terms and agreements when using this technique. Always refer to the most recent and official Microsoft documentation for the most accurate and up-to-date information.

Remember : this method is not a hack or illegal; it’s a legitimate way to customize Windows installation for specific scenarios. The ei.cfg file essentially tells the Windows installer which edition to install, and Microsoft has documented this process.
