Hello,





There is still a way to search for your product key. Kindly follow the steps below for you to know your product key:

• Press Windows key + X
• Click Command Prompt (admin)
• Enter the following command: wmic path SoftwareLicensingService get OA3xOriginalProductKey
• Then hit Enter

The product key will be revealed, copy the product key then enter it.

Give us an update on what happens.

 

Enter a Product key

Hi MohammadMoharram,

Thank you for writing to Microsoft Community Forums.



To get clarity on this issue and assist you with appropriate troubleshooting steps, kindly reply with the answers to the questions below.

1. What is the version of Windows installed on your PC, is that Windows 10 Home or Pro?
2. Are you receiving any error message, when you are trying to activate your Windows 10?
3. Have you purchased the product key for Windows 10 while purchasing the laptop?
4. How did you run windows recovery?

However, I suggest you to refer this thread article on
using the Activation troubleshooter and
Activation in Windows 10, and check if that helps.



I look forward to hearing from you soon.

Regards,

 

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).
