Unlike Windows 7 products, there are no external, visual indicators of the Product ID or Windows version for
which the computer is 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.
In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 10 Pro
license downgrade rights.
