iso image - Does the Windows 10 ISO have a EI.CFG file for changing the edition?

The ISO image of both Windows 7 and Windows 8 had a file ei.cfg that could be modified to allow a user to install any edition of Windows.

Since I am going to install the Windows 10 operating system on several different machines with different configurations, I would like to minimize the number of downloads I have to do in order to save bandwidth and time.

I would therefore like to know if the Windows 10 ISO also have this file for changing the windows edition (ei.cfg) or I have to download each one separately.

Answer

I found that the Windows 10 does not have a ei.cfg file like in Windows 7 and Windows 8. Microsoft however provides two "All Editions" versions in 32-bit and 64-bit flavors. Also, due to the layout of the disc, it is possible to combine both the 32-bit and 64-bit versions of both of the "All Editions" discs in order to create a "Universal Install Disc"

I explain below how to obtain 32-bit or 64-bit All Editions disc and then a Universal Install Disc

How to download a Windows 10 All Editions Disc

1. With a web browser running on any operating system apart from Wiindows 7 or Windows 8 (e.g. OSX, Linux, Android, Windows XP), visit https://www.microsoft.com/en-us/software-download/windows10ISO.
   You can also modify your User Agent to falsely report your operating system if your browser supports it before clicking on the link.


2. Select the edition you want to download (i.e. Windows 10, Windows 10 KN, Windows 10 N, Windows 10 Single Language) and then click Confirm.


3. Select the language you want to download and then clck Confirm.

You will now be presented with two buttons for downloading the 32-bit and/or 64-bit versions of Windows 10. The links are valid for 24 hours after which they expire.

How to create a Windows 10 Universal Install Disc

1. Download both 32-bit and 64-bit versions of Windows 10 as shown above.


2. Download the disc layout from here.


3. Extract the Win10MultiIsoBase.zip file to a destination of your choice.


4. Merge the contents of the Windows 10 ISO images with the extracted files by extracting the contents of the 32-bit ISO into the x86 folder and the 64-bit ISO into the x64 folder.


5. Using ImgBurn, create an ISO image with the merged data.
   Remember to make the image bootable by following these steps:
   
   
   
   • Select the Advanced tab and then the Bootable Disc tab.
   
   
   • Check the Make Image Bootable check box.
   
   
   • Download and use this file as the Boot Image.
   
   
   • Choose 80x86 as the Platform ID.
   
   
   • Enter Microsoft IMAPIv2 as the Developer ID.
   
   
   • Enter 07C0 as the Load Segment.
   
   
   • Enter 8 as the Sectors to Load.
   
   
   
   


6. Optionally, burn the ISO to disc. You will have to use a DVD DL since the image file generated will be larger than 4.7 GB. After completing my download and examining the ISO, I have found that there is no ei.cfg file.

I am still searching for a way to achieve 'universal' install capability and I'll update this answer when I find one.
