The term "personal computer" means a fully assembled computer system that includes at least a CPU, motherboard, hard drive, power supply, and enclosure. When replacing any component of the computer other than the motherboard, the user retains the right to use the OEM license. When replacing the motherboard, a new license is required, except in cases of replacing the motherboard with a similar or identical one during warranty repairs.
The user receives the rights to use OEM versions on the basis of a license agreement with the end user, concluded between the end user and the system collector. In particular, this agreement entitles the end user to the technical support of the product that the system provider is obliged to provide. The end user license agreement for the use of the OEM product is often distributed electronically and is displayed when the product is first launched. It is forbidden to rent or temporarily use a computer with the OEM version installed without purchasing additional licenses that give the right to rent Microsoft software (Rental Rights). The user has the right to transfer the OEM version together with the equipment. When transferring a computer with the OEM version installed, the owner must also transfer the full set of the OEM license.
