Win 8 RP keyless installation method

Windows 8 Release Preview is no longer the same as Windows 7 and can be installed even without a serial number. Instead, you need to fill in the serial number as in Office 20120 to install it. Do you skip the step of entering the serial number to install Windows 8 Release Preview?

As shown in the figure below, there is no skip button in the interface for entering the product key, and the next step is the state that the gray cannot be clicked. Is there a way to skip this step? In fact, there is a very simple way:

Now everyone generally uses the U disk installation method, then just use Notepad to edit a name called EI.CFG The text file (note the .txt extension), then place it in the Windows 8 installation file Sources folder. The contents of the EI.CFG file are as follows:
[EditionID] PROFESSIONAL
[Channel] Retail
[VL] 0
If you use the Burn CD to install, edit the ISO image using UltraISO and other software. The EI.CFG file can be used.
The effect after adopting this method is: automatically skip the step of forcibly inputting the product key, and directly start the installation process; after the installation is completed, the user is prompted to input, you can bravely click & skip; " >
