Before continuing, we must clarify that, in terms of functions, the three types of license are identical, that is, by installing an OEM version, a RETAIL version, or a BINDABLE version, your Windows or your Office works as the same way. But let’s get to know the differences a little more in detail.

These licenses are used by equipment manufacturers (Original Equipment Manufacturers). They are used not only by large manufacturers such as IBM, Asus or Dell, but also by small integrators and computer stores, where we can buy computers with custom configurations. This type of license is linked to the PC where it is installed for the first time and forever. It cannot be used on another PC.Cannot be used to upgrade the system: The OEM copy of Windows cannot be used to upgrade an older version of Windows. For example, upgrading from Windows XP to Windows 7 or from Windows 7 to Windows 8.1. The license is designed for installation on new computers, which do not yet have an operating system.

These are the standard consumer licenses for Windows or Office. They have been designed for normal computer users, who intend to purchase a license to upgrade their machine to a new version of Windows. This type of license allows the user to install Windows on any computer and even change it to another, but the same license can only be installed on a single computer at a time.
