Often System Builders always use the same Windows 10 code (see DELL, ASUS, ACER etc.). These license keys are digital and integrated into the BIOS of the computer together with the serial of the PC. It is only used by System Builders with Microsoft. The true OEM (Original Equipment Manufacturer) license is a license sold with the PC.
There is a lot of confusion about this license and it is often confused with the OEI license.
