Windows 10 product keys and activation - and the KMS angle

Changing the product key to the generic Windows 10 product key will reset activation to the standard retail channel for activation. It might just activate (if there was a previous digital license for Windows 10 for that computer established with Microsoft). Once Windows 10 is back on the retail activation channel, then more than likely changing the product key to the Windows 8 product key using the same method may work.

 

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.

 

New DELL laptop- Windows Product Key

Hi and thanks DaveM121 for the prompt reply.

I followed the instructions supplied by the DELL email but in the end Windows would not automatically activate. I just found an answer by following this below google result instructions:

Find Windows 10 Product Key on a New Computer

1. Press Windows key + X.
2. Click Command Prompt (Admin)
3. At the command prompt, type: wmic path SoftwareLicensingService get OA3xOriginalProductKey. This will reveal the product key. Volume License Product Key Activation.

I copied the key and entered it into the option to change product key (not that one was entered as it said it was inactive in red text). FWIW, I never got a product key in any form suggested by the problem solving suggestions
wormhole link I found in Settings. Apologies if this is a basic newbie issue. It has been doing my head in for the last couple of hours.

Anyway, greatly appreciate your time. Thanks again DaveM121.
