A clean Windows 10 install is the best solution to resolve OS problems that are faced by users after the free upgrade. Many users who have tried clean Windows 10 install were unable to install Windows Pro edition on their computer.
Microsoft is offering a unified Windows 10 ISO file for Home and Pro users; it means no separate ISO files for Home and Pro users. It means during the installation you should get an option to select between Home and Pro edition. However, the Windows setup automatically installs Windows 10 Home edition and the user does not get the option of selecting Windows Pro edition during the installation.
Note: Windows Home edition users should not try installing Pro edition as your older Windows license key will only work with Windows 10 Pro edition.
How to Get Windows 10 Pro Option During Installation
The solution to this problem is creating an edition configuration (EI.cfg) file and including it in the Windows 10 ISO file. The EI.cfg files tell Windows 10 setup to install Home or Pro edition on your computer. In simple words, after including the EI.cfg file in Windows 10 ISO, the Windows setup will display the prompt asking you to select the Windows 10 edition to be installed. The solution can also be used by Windows users who had Windows 10 home edition installed on their computer but want to force Windows 10 Pro install on their computer.
