OEM Software Notice:
- To purchase OEM System Builder license, you must be a System Builder and accept the System Builder License. “System Builder” means an original equipment manufacturer, an assembler, a Refurbisher, or a software preinstaller that sells the Customer System(s) to a third-party. OEM software may ONLY be distributed with a fully assembled computer system.
- For a desktop operating system or application software, the software also must be preinstalled on the hard drive of the fully assembled computer system, using the OEM Preinstallation Kit (OPK).
- The system builder who installs the software is responsible for the provision of end-user support.
- The OEM license is tied to your motherboard, meaning if you change your motherboard you will require a new license.
- OEM keys only work on a new Windows installation and will not activate or upgrade an existing installation of Windows.
