Lost Windows Activation Product Key

I recently lost my Windows 10 pro Activation product key and now Microsoft wants me to activate my windows but now i dnt have any product key please suggest me the way i dnt want to lost my all data...

 

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.

 

After restoring PC the Product Key is lost. How do I recover it?

Hi Jack,

Welcome to Microsoft Community.



I can understand how frustrating it could be when things go unusual.

We suggest you to activate using phone activation method.

Please follow the below furnished step to activate windows manually:

• Open run command by pressing Windows + R and type “slui 3” and hit enter.
• You will notice a pop asking to for product key. Please enter the product key and ensure that there should not be any errors, while entering the product key.
• Once authenticating, it will give confirmation message on successful windows activation
• If problem still persist, I would suggest you to open run command again by pressing
  Windows key +R type “slui.exe 4” and press enter. Please follow the prompts to activate the windows copy by phone.
