Windows 10: MicrosoftFSX with the product number, how can i activate without it

after moving a few times i lost my product number for MS FSX how can i activate without it

Activate windows 10 after re-installing (I have lost my product key)

I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

If not, please suggest me a solution or a workaround.

 

Is it possible to use a Windows 10 product key to activate a Windows 7 installation?

According to Microsoft, you can't use your Windows 10 keys. You will have to call Activation Support, provide proof that you have a license with downgrade rights, and they will provide a response to the activation challenge that will result in a one-time activation of an install.
