• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed

The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the

licensed. Instead, the Product ID is recorded in the computer firmware. Whenever a Windows 10 product is
installed, the installation program checks the computer firmware for a valid, matching Product ID to complete
the activation.
