Windows 10: My product key is lost.

I am not able to find my serial/product key, it is not in my emails, and I threw away my box. Can my problem be solved?

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.

 

My Product Key

I have hit another roadblock in my marathon two-day attempt to restore the laptop that Windows 10 destroyed. I do not have the product key for the device, so cannot even revert to Windows 8.1. The product key is not shown in the Amazon purchase listing for the device, and I long ago lost the paperwork. Is there any way I can look it up (keeping in mind of course that the device itself is utterly unusable in its current state)?
