Where can you find Windows 10 product key from your Computer?

Printed on a sticker:

Retail Microsoft product keys are usually on a brand sticker located inside the case with the CD/DVD, or on the back. If you bought a computer installed with Windows 10, you may find the serial key on the Microsoft-branded sticker on your PC case.

Sent with Email:

If you purchased Windows 10 online, you may find the license key is included in an email that Microsoft sent you at the time of purchase.

Stored on Windows Registry:

To view your Windows 10 product key in the Windows Registry: Press "Windows + R" to open Run, enter "regedit" to open Registry Editor.

Find the DigitalProductID by this way: HKEY_LOCAL_ MACHINE\SOFTWARE\Microsoft\windows NT\Currentversion.

You will find the DigitalProductID in registry, but you can't read it normally without a third party help.

Stored in PC's UEFI firmware:

The activation key for the version of Windows 10 is stored in the computer's UEFI firmware or BIOS. When you install or reinstall the same edition of Windows 10 (Windows 10 Pro, Windows 10 Enterprise, or Windows 10 Home) on a same computer, you do not need to enter the product key to activate it in a normal way. It will be activated automatically without entering product key after the installation.
