PROBLEM REASON:

Actually Windows 10 setup automatically detects the edition type of previously installed Windows version in your computer and then it installs the corresponding edition of Windows 10. For example, if you had Windows 7 Home or Windows 8/8.1 core edition installed in your computer previously, Windows 10 setup will automatically install Windows 10 core (Home) edition in your computer.

One more thing! If your computer originally came with core or home edition of Windows 7/8/8.1 and you forcefully upgraded it to Windows 10 Pro edition when Windows 10 RTM released and now you try to clean install Windows 10 version 1511, it'll still install Windows 10 core (Home) edition as it'll detect the product key stored in BIOS which is obviously associated with core or home edition of previous Windows version.

PROBLEM SOLUTION:

The solution would be forcing Windows 10 setup to provide selection screen so that we can choose between Core (Home) or Pro editions of Windows 10 or forcing Windows 10 to automatically install Pro edition in our computer.

NOTE: Please keep in mind if you have product key of core or Home edition of Windows 7/8/8.1 and you previously activated Windows 10 core edition in your computer and now you try to install Pro edition of Windows 10, it'll not activate after installation as your computer's hardware ID is associated with Windows 10 core (Home) edition.

We can force Windows 10 setup to install our desired edition of Windows 10 by adding a new file "ei.cfg" in Windows 10 setup ISO image. This file tells Windows setup about which edition of Windows should be installed in the computer.

If you remember long time back when Windows 7 was released, we told you about a similar thing. Windows 7 setup was also automatically installing applicable edition in computers and was not giving any choice to select desired Windows 7 edition. The solution was deleting "ei.cfg" file from Windows 7 setup ISO file:

How to Choose Desired Windows 7 Edition / Version During Setup?

Now we are going to use the same "ei.cfg" file to force Windows 10 setup to install Pro edition instead of core (or Home) edition in our computer.

Windows 10 setup ISO doesn't contain "ei.cfg" file so we'll need to create the file manually and set its content to install Pro edition. Check out following steps to install Pro edition of Windows 10 in your computer:

STEP 1:

First of all we'll need to extract the content of Windows 10 setup ISO file. You can extract it using 7-Zip. It'll take some time in extracting the whole ISO file.

STEP 2:

Now open Notepad and copy/paste following piece of code in Notepad:

[EditionID]
Professional
[Channel]
Retail

You can also totally skip the [EditionID] part in the "ei.cfg" file so that Windows 10 setup asks you to choose desired edition at the time of clean installation:

[Channel]
Retail

Now save the file with the name "ei.cfg" (use the double-quotes "" while saving the file otherwise Notepad will create a text file with the name ei.cfg.txt).

STEP 3:

Now copy the "ei.cfg" file and paste it into Sources folder of Windows 10 setup folder which you got after extracting ISO file using 7-Zip.


STEP 4:

Now you can create bootable USB drive or burn the files to a DVD and install Windows 10 Pro edition without any problem.
