Ever since the release of Windows 8, all PC manufactures have started embedding product license key into the BIOS/EFI. That is, computers pre-installed with Windows 8, Windows 8.1, and Windows 10 don’t display product key information or Certificate of Authenticity (COA) sticker on the backup of the computer or in the battery bay.
