Preliminary information

Before getting to the heart of the topic, then going to find out how to find the Windows 10 product key, it seems only right to explain what we are talking about, precisely. In case you are not aware of it, the Product Key is an alphanumeric code consisting of 25 characters allowing activate Windows and which is used to determine theauthenticity of the copy of the operating system in use.



The Windows Product Key is formed like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. It is requested during the installation phase of the operating system but, if necessary, it is possible to decide to enter it later.

The way in which the Product Key is communicated to you varies depending on how you purchased Windows 10, whether the system came pre-installed on your computer or if the copy in question was purchased at a later time. In the first case, it is on a label attached to the computer, otherwise it can be communicated electronically or be present in the physical package of the operating system: I will tell you more about it in a dedicated chapter of this tutorial.

Having made the necessary clarifications above, let's take action. The first way to find the Windows 10 Product Key that I invite you to try is to go to the command line, using the Command Prompt. How you do it? I'll explain it to you immediately.

To begin with, launch Command Prompt with administrative privileges by clicking the Start button (I cheer with the windows flag) which is located at the bottom left of the taskbartyping "cmd" in the displayed search field, by right clicking on the displayed result, selecting the item Run as administrator from the menu that appears and clicking on the button Yes in the window that is shown on the screen.



In the Command Prompt that you now see, enter the string you find below, followed by pressing the key Submit sulla tastiera from the PC.

How to find the Windows 10 product key from the registry


You can also find the Windows 10 product key from system log, but just fit encrypted. For the purposes of this tutorial, therefore, this is not particularly useful, but for the sake of completeness of information it is my duty to tell you how to proceed even in this case.


First, invoke Registry Editor by clicking on the Start button (I cheer with the windows flag) located at the bottom left of the taskbar, by typing regedit in the search field that appears and clicking on the relevant suggestion. Then click on the button Yes in the window you see appear on the screen.

Now that you see the Registry Editor window on your desktop, go to the following path, selecting the relevant items that you find in the tree structure on the left: HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > Current Version.

You will find the serial number of your copy of Windows 10 under the item DigitalProductId, but as I told you before, this will be in encrypted form.

Other ways to find the Windows 10 product key

In alternative As I have already described to you in the previous lines, you can find the Windows Product Key in the following ways, which differ depending on how you purchased your computer or your copy of the operating system.

  • If you bought a new PC with Windows 10, you will find the Product Key on the sales package of the computer or on a special certificate included within it, which is called the Certificate of Authenticity. Also in this case, you can also find the Product Key reported on a special label stuck directly on the computer case (if it is a desktop PC) or on the body, generally at the bottom (if it is a laptop).
  • If you purchased a copy of Windows 10 from an authorized reseller, find the Product Key on a card or label inside the OS purchase package.
  • If you purchased a digital copy of Windows 10 from an authorized reseller, find the operating system serial in the confirmation email received after purchasing Windows 10 or in a digital binder, accessible via the retailer's website.
  • If you purchased a digital copy of Windows 10 from a Microsoft website, the Product Key appears in the confirmation email received after purchasing the digital copy of the operating system.
  • If you have upgraded for free from Windows 7 or Windows 8 / 8.x to Windows 10, you have a digital license directly associated with your computer, rather than a Product Key.
  • If you purchased a different version of Windows 10 from the OS App Store, you have a digital license, rather than a Product Key, and you can use it for activation.

For further details, you can refer to the appropriate information web page that you find on the Microsoft website.
