Where to Find Your Windows Activation Key?
You can find your windows activation key by four methods, they are given below:
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, you may find the serial key on the Microsoft-branded sticker on your PC case.
Sent with Email:
If you purchased Windows 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 product key in the Windows Registry: Press “Windows + R” to open Run, enter “Regedit” to open Registry Editor.
Find the DigitalProductID in 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 third party help.
Stored in PC’s UEFI firmware:
The activation key for the version of Windows is stored in the computer’s UEFI firmware or BIOS. When you install or reinstall the same edition of Windows (Windows Pro, Windows Enterprise, or Windows Home) on the 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.
How does Windows Activation Works?
Windows will prompt you to activate with Microsoft after you install it. When you activate over the Internet, your copy of Windows checks in with Microsoft and reports its product key. If your Windows product key is non-genuine (in other words, a pirated key) or is being used on another computer, the activation process will fail.
Windows can also be activated with a phone call. Windows provides a code you type in over the phone, and you’ll have to enter the code it responds with into your computer. You can also talk to a real person, which is useful if the activation process is failing. For example, if you’re moving Windows to a new computer, you may have to talk to a real person and explain the situation before they’ll allow Windows to activate.
“Significant” hardware changes can also trigger the Windows activation process again. For example, if you swap out multiple components on your PC at the same time, you may have to go through the activation process. Microsoft hasn’t explained exactly which hardware changes will trigger this.
