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.

• UltraISO recommended to edit|save your .iso, preserving 'bootable' image
