How to recover Windows 10 serial number

windows-10-activation

Although Microsoft has announced the ability to link a Windows 10 serial number to a user account, there are cases in which we will not be able to use this functionality. Either because we do not have, nor do we want to have an Outlook account, or because we do not have a connection to the network license server, Having the key of our Windows 10 available is always recommended.

This key is what we must introduce each time we perform a new installation of the operating system. If you use an Outlook account and you already have the password associated, this step will not be necessary. In other cases, you must enter the number to license the system and be able to use all the functions. With this guide we will learn how to recover Windows 10 serial number.

Little by little Microsoft is opening up to user requests and it is finally possible to associate a serial number with an account. If for any reason we cannot make use of this capacity and we prefer to have our activation number safeguarded but we do not know how to obtain it, follow these steps carefully.

Retrieving Windows 10 Serial Number

  • Firstly, we will press the Windows 10 Start button and we will introduce the word regedit to display the Windows Registry Editor, or we will press the Windows + R key combination and enter regedit as command.
  • Once the Registry Editor is open, we will sail to the route: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ SoftwareProtectionPlatform where we will find, under the key BackupProductKeyDefault the key of our Windows 10 in clear text.

Be very careful when guarding this password, since once it is registered against a user's account, it would be very difficult for you to claim ownership of it again. Also know that Microsoft does not currently support more than one Windows 10 operating system license per user account. We assume that this restriction will be opened in the future, but at the moment there is no news that this will happen.

Associating a serial number with a Microsoft account

To associate a Windows 10 operating system key to our Microsoft account, it is as simple as following these steps:

  • We must access the option Configuration from the Start Menu, by pressing the Start button. A new window will be displayed where we must choose the option Updates and security, as we show you in the following image below.

  • Next and once clicked on Update and security, a new window will appear where we must go to Activation menu, to display the operating system log options. We see that our device is activated with digital rights, which refers to the fact that we have updated the system using the original license of the equipment, for example, from Windows 7 or Windows 8 / 8.1 to Windows 10. Once in this menu, we will click on the text which indicates Sign in with a Microsoft account instead, which we can see on the right side of the screen.

  • Next, to assign the Windows 10 license to our account, we will select the option Sign in with a Microsoft account. Instead we will enter the necessary data.

Once these steps have been followed, the license of our Windows 10 system will be linked to our personal account. This is very useful since currently Microsoft's key generation for systems licensing is linked to the computer's motherboard. But if we change computers or said component is damaged, the key as such will not be valid by entering it in the system installation.

However, If the license has been linked to our account, it will be enough for us to log in to the computer so that it is automatically licensed to us. Without a doubt, a very simple step that avoids the cumbersome mechanisms of the past to register and verify the authenticity of our operating system.
