(Vista-Win10) If not known edition, branding only takes place.

Objective - add $oem$ folder to .iso /usb.

$oem$ method can be used to apply activation & manufacturer brand to your Win10 Win 8.x Win 7 Vista '.iso'/usb
NOTE:- PC needs (Win8.x and Win10 'OEM-DM' Win7 '2.1 slic' Vista '2.0 slic') bios to apply genuine oem activation.

How To:
Win 10
Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and edit|save iso. OOBE.cmd (Install.cmd) will extract embedded 'OEM-DM' serial from bios (if exists), and apply the serial during installation.
Win8.1
Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and add custom 'ei.cfg' file to the same 'sources' folder and edit|save iso. Windows will install the edition identified from 'ei.cfg' file. (Project 'Options' folder includes 'ei.cfg' instructions). OOBE.cmd (Install.cmd) will extract embedded 'OEM-DM' serial from bios (if exists), and apply the serial during installation.
Win8.0
Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and edit|save iso. Windows will install the edition that matches the embedded 'OEM-DM' serial in your bios (if exists).
Win7
Place the downloaded '$oem$' folder in the 'sources' folder of your 'clean' iso, and delete the 'ei.cfg' file from the same 'sources' folder and edit|save iso... during install you will have option to select the edition of 'Win7' you want installed (ie. Starter Home Basic Home Premium Pro Ultimate)... if you don't delete 'ei.cfg' file, that's OK, just 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 exists) from the same 'sources' folder and edit|save iso... during install you will have option to select the edition of 'Vista' you want installed (ie. Starter Home Basic Home Premium Business Ultimate)... if you don't delete 'PID.txt' file, that's OK, just means serial used on that file will determine edition installed.

Please read the 'readme' files included in the download folder, for additional information
UltraISO recommended to edit|save your .iso, preserving 'bootable' image
