Win8.x|Win10

Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and add a custom 'ei. cf file to the same 'sources' folder and edit|save iso. Windows will install the edition identified from the 'ei.  cf file. (Project 'Options' folder includes 'ei. Cf instructions). OOBE.cmd will call a tool to extract the embedded 'OEM-DM' key from bios (if it exists) and apply the serial during installation.

Win7

Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and delete the 'ei.  cf file from the same 'sources' folder and edit|save iso… during install, you will have the option to select the edition of 'Win7' you want to be installed (i.e., Starter • Home Basic • Home Premium • Pro • Ultimate)… if you don't delete 'ei. The Cf file is OK; it means Ultimate will install by default.

Vista

Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and delete the 'PID.txt' file (if it exists) from the same 'sources' folder and edit|save iso… during install, you will have the option to select the edition of 'Vista' you want to be installed (i.e., Starter • Home Basic • Home Premium • Business • Ultimate)… if you don't delete 'PID.txt' file, that's OK, means serial used on that file will determine edition installed.
