Windows 10: Windows 10 De-activated, Unable to find Product Key

My version of Windows 10 de-activated itself following an update, and I'm unable to re-activate it. I cannot relocate my key in the registry (there simply is no value for it), despite this computer using Win 10 for 5 months without issue. I am very confused.

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.
