Unlike Windows 7 PCs, computers pre-installed with an edition of Windows 8 and Windows 10 don’t have a Certificate of Authenticity (CoA) sticker with their original product key printed on it. This is because, the product key is embedded in the PC’s UEFI firmware and can’t be seen just by accessing the UEFI. While using a Windows 10 PC, you don’t need to view or backup your Windows 10 product key as we can clean install or reinstall the same edition of Windows 10 on the same PC and activate the copy of Windows 10 without having to enter the product key. That said, there might be instances where you want to view your Windows 10 product key. May be, you want to uninstall the product key and use it on a different computer, or may be, you want to backup the product key before making substantial changes your PC’s hardware. There are plenty of software out there to view or retrieve your Windows product key. While not all of them work great on Windows 10 and some of them out there even show a different key than the actual product key, here are three methods to view or retrieve your Windows 10 product key for free.
