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.

 

Find original win 8 product keys used?


That key should still be usable to install 8.1. Technically, since you used it to install Windows 10, if you use it to install Windows 8.1, you should stop using the version of Windows 10 you activated with it. As far as I know though, its not enforced in any manner.
I upgraded my laptop from 8.1 Pro (MSDN Retail key) to windows 10 Pro. Then months latter, reinstalled 8.1 Pro with the original key on that laptop. It activated with no issues. I then clean installed 10 Pro on that same laptop with a skip key and it activated with no issues. The 8.1 key was not blacklisted etc. I don't "think" its tied to the Windows 10 activation in any way. No way of proving it though.
I keep a detailed list of what product keys I've used on what PC. Windows and office etc. Saves me from any guess work latter on. *Wink
Then if I have to reinstall a previous OS I can use the original key and not worry about activation issues.

 

Lost Original windows Product Key

Here are the possibility.

• You can check the product key sticker under the laptop.

• If your laptop came with pre-installed Windows 8/8.1/10 you never need to enter the Windows product key manually, It's usually embedded in your UEFI/BIOS. Just install a fresh copy of Windows 10 and install all the drivers then it's activated automatically
  once you connect to the internet.

For drivers, You can always check the vendor's website.
