How to find out my Windows 10 product key

22 mayo, 2021

Forever it is interesting to know your Windows 10 product key, but if you experience problems on your computer, you plan to change the hard disk or you want to take advantage of your system license to install it on another machine, you need it directly. Because if you are going to reinstall in all probability you will have to enter it.

You can access this twenty-five character code divided into groups of five separated by hyphens using a simple application in the operating system itself or looking for it in different ways considering how you got your copy of Windows 10.

In spite of everything, you must bear in mind that it may be the case that the activation can be carried out through a digital license that did not require entering a product key. But this will also depend on the form of acquisition and is not applicable to all cases as Microsoft makes clear in its support.

Four ways to get your Windows 10 product key

  • If you bought your copy of Windows through an authorized dealer, the product key is on a label or card inside the box that Windows shipped in.

  • If windows came with the purchase of a new equipment, the product key will be pre-installed on the machine and can be found in the package in which the equipment was sent or in the certificate of authenticity attached to the device. It will usually be on a sticker located on the bottom of the laptop, as well as on the sides or top of a tower.

  • If you got Windows of a digital copy of a Microsoft website, the product key came to you in a purchase confirmation email. However, if it was distributed as a digital license, please note that it does not include this code.

  • If you have Windows 10 because you upgraded to him for free when offered by Redmond, from Windows 7 or Windows 8.1, you should also have a digital license instead of a product key.

More options to find the Windows 10 key

Sometimes these methods recommended by Microsoft are not enough because none works in our case. At this point we can contact the manufacturer of our equipment to provide us with information on where to find the key, if our copy of Windows has it, or try these other methods.

  • Going to the system registry: HKEY _ LOCAL _ MACHINE / SOFTWARE / Microsoft / Windows NT / CurrentVersion / SoftwareProtectionPlatform and in the list of variables we look for “BackupProductKeyDefault”. There it should be.
  • Running PowerShell, as highlighted in the comments, introducing the following: powershell “(Get-WmiObject -query ‘select * from SoftwareLicensingService’). OA3xOriginalProductKey”.

If you are going to change hardware …

If you are about to make a major hardware change, such as replacing the computer’s motherboard, you should know that you can link your Microsoft account to the Windows 10 digital license on the device. As Microsoft explains, “this can help you reactivate Windows using the Activation Troubleshooter.”

You can do it like this:

  1. We go to Start> Settings> Update and security> Activation and there we select “Activate an account”.

  2. You log in with your Microsoft account account and password and also type your account password on the computer if both are not connected.

  3. After add your Microsoft account, the activation page will tell you that “Windows is activated with a digital license linked to your Microsoft account.”

After making the hardware change, you will have to go back to the “Activation” section of the Windows settings and select the option “I have recently changed the hardware of this device”. There, you can link the computer to your Microsoft account again, to which you have the Windows 10 digital license linked.
