One of the things I quite miss the old way in Windows 7 is to skip the product key input during the installation. I believe there are reasons why Microsoft has put a stop sign on this but there are also valid situations where skipping a product key during the installation also makes sense.
Basically, you will need to extract the files from Windows 8 ISO file, add a file named ei.cfg in sources folder, with the following content, and re-wrap up the ISO file.
Edition ID can be Core, Pro, or Enterprise, depending on the ISO image file you have. And Channel can be Retail or OEM, while VL can be set to 1 for true or 0 for false.
But I found it will be a lot easier if you have created the bootable USB drive, since you can create and edit the ei.cfg file directly into the USB file system.
Once you have the media ready, you can boot off it to start the installation process again. All steps are the same, until you reach to the point where you put in the product key. Now, you will see there is a Skip button you used to see all the time back to Windows 7 time. Clicking that will lead you to finish up the installation without typing in a valid product key.
Sorry, couldn’t take a clearer shot but you get the idea.
While skipping a product key during the installation is nice, it won’t get you too far as it used to be. You will need your windows 8 activated before customizing your Windows, i.e. PC Settings.
Go to System window (type “system” in start screen), you will notice the message indicating that Windows is not activated at near the bottom of the window.
To activate, you can click the link “View details in Windows Activation”.
Note that the error code under Activation details section indicates that you don’t have a valid product key to activate your Windows 8 at the moment.
Click on Activate with a new key button, and that’s where you will see the following screen we mentioned in our early post how to change product key and activate windows 8.
