Preliminary information

Before getting to the heart of the matter, then going to find out how to find the Windows 10 product key , it seems right to explain what we are talking about, precisely. If you are not aware of it, the Product Key is an alphanumeric code consisting of 25 characters which allows you to activate Windows and which is used to determine the authenticity 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, possibly, you can decide to enter it later.

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

You can also find the Windows 10 product key from the registry , but only in encrypted form . For the purposes of this tutorial, therefore, it is not particularly useful, but for the sake of completeness of information it is my duty to indicate how to proceed in this case too.

First, call the Registry Editor by clicking on the Start button (the one with the Windows flag ) located at the bottom left of the taskbar, typing regedit in the search field displayed and clicking on the relevant suggestion . Then press the Yes button 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 heading DigitalProductId , but as I already told you before, this will be in encrypted form.

Other ways to find the Windows 10 product key

As an alternative to how I have already described you in the previous lines, you can manage to 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 purchased 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 inside, which takes the name of Certificate of Authenticity. Also in this case, you can also find the Product Key on a special label stuck directly on the computer case (if it is a fixed 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 on a label inside the OS purchase box.
  • If you purchased a digital copy of Windows 10 from an authorized reseller , you can find the operating system serial number in the confirmation email received after purchasing Windows 10 or in a digital binder, accessible via the reseller’s website.
  • If you purchased a digital copy of Windows 10 from a Microsoft website , the product key is listed in the confirmation email received after purchasing the digital copy of the operating system.
  • If you upgraded free from Windows 7 or Windows 8 / 8.x to Windows 10 , you have a digital license directly associated with your computer, instead of a product key.
  • If you purchased a different version of Windows 10 from the OS App Store , you have a digital license instead of a product key and you can use the latter for activation.

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

Programs to find the Windows 10 product key

Putting into practice the indications that I have given you in the previous lines, you have not been able to trace the Product Key of your copy of Windows 10 and would you like to know if there is any other solution suitable for the purpose? The answer is yes.

In fact, to obtain the information you need, you can also rely on one of the special programs that you find below.

NirSoft ProduKey

NirSoft ProduKey Windows 10

The first software to find the Windows 10 product key that I recommend you try is ProduKey , developed by NirSoft . It is one of the most famous in the category. It allows you to recover the serial number of Windows and also that of the Office family products in a very simple way (however it does not allow you to view the desired information if you use Microsoft Volume Licensing). It is free and does not require installation to function.

To use it, connected to its website , scroll to the bottom of the displayed web page and select the Download ProduKey link  (In Zip file) . Also download the Italian translation for the program interface by clicking on the Italian link in the appropriate table.

When the download is complete, extract both the ZIP archives obtained in a folder of your choice, then start the ProduKey.exe file  to start the program. Now that you see the software window on the desktop, find the wording Windows 10 in the Product name column : in the relevant Product key column you will find the Product Key.

If you want, you can also choose to save the data obtained as a text file: to do this, select the serial using the key combination Ctrl + A and click on the floppy disk icon , which is located at the top left.

If instead of saving the Product Key you intend to copy it to the Windows clipboard, right-click on it and select the Copy Product Key item from the menu that is shown to you. You can then paste the serial where you see fit, using the key combination Ctrl + V .

Lazesoft Windows Key Finder

Another excellent program you can rely on to recover the Windows 10 product key is  Lazesoft Windows Key Finder , free, no-install and open source. It works in a similar way to the software I already told you about in the previous lines: it allows you to find the serial of all versions of Windows and Office.

To download it to your computer, go to the Lazesoft Windows Key Finder website and click on the Free Download Now button , located in the center of the web page displayed.

When the download is complete, start the .exe file obtained and wait for the program window to be visible on the screen. You will then find the Product Key of your copy of Windows in the appropriate box, on the left.

If you want, you can save the information obtained as a text file by clicking on the Save button . Alternatively, you can print the serial by pressing the Print button . Very easy, right?

SterJo Key Finder

If, for any reason, the programs I have already told you about did not have the desired effect and therefore you need an alternative solution, I suggest you to test  SterJo Key Finder : it is another free application that allows you to recover the Windows and Microsoft Office serials, as well as those of various other software (such as Photoshop and AutoCAD) and video games. It requires no installation and is very easy to use.

To download it to your PC, go to the program’s website and click on the Portable button , which you will find at the bottom of the page.

When the download is complete, extract the ZIP archive obtained in a folder of your choice , start the .exe file inside it and click the Yes button in the window that is shown on the desktop.

Now that you see the main window of SterJo Key Finder, find the Product Name column and the wording Windows 10 [edition name]> Key : in its correspondence, in the Product Key column , you will find the Product Key of your copy of the operating system.

If you want, you can export all the Product Keys that the program has identified in a text file: to do this, click on the floppy disk icon located at the top left of the program window.

If, on the other hand, you want to copy the selected serial to the Windows clipboard, click on the button with the two sheets and the arrow that you always find at the top, on the program toolbar.
