    To change your product key and upgrade from Windows 7 to Windows 10, you can follow these steps:

    1. Manual Entry: Right-click on the Start menu and select Run. In the Run window, type ms-settings:activation and press OK. From there, select Change product key and enter your new product key.
    2. Using Command-Line Tools: You can also use the changepk.exe command-line tool to upgrade your device. Open Command Prompt as an administrator and run the following command:
         changepk.exe /ProductKey <your_product_key>
      
      Alternatively, you can use slmgr.vbs with the following command:
         cscript.exe c:\windows\system32\slmgr.vbs /ipk <your_product_key>
      
    3. Upgrade through Microsoft Store: If you do not have a product key, you can upgrade through the Microsoft Store. Right-click on the Start menu, select Run, type ms-windows-store://windowsupgrade/, and follow the on-screen instructions.

    Make sure that the product key you are entering is valid for the edition of Windows 10 you are trying to upgrade to. If you encounter any errors, it may be due to compatibility issues with the existing Windows 7 installation or the product key itself.

    Dear Anthony Davis

    Thank you for your question and for sharing the details in Microsoft Q&A Forum. 

    I understand how important it is for you to upgrade your system smoothly, and I’m here to help clarify the situation and guide you through the next steps. 

    When upgrading from Windows 7 to Windows 10, changing the product key directly on Windows 7 will not work. This is because Microsoft does not support upgrading by simply entering a Windows 10 key on Windows 7. Before we proceed, please take a moment to review the previous suggestions provided by AI, as they are quite helpful and worth trying. If those steps do not resolve the issue, here are the possible scenarios and solutions: 

    1. If you are trying to upgrade from Windows 7 using a Windows 10 Product Key 

    • You’ll need to install Windows 10 first. 
    • Please download the Media Creation Tool from Microsoft’s official site. 
    • Choose Upgrade this PC now and follow the steps. 
    • After installation, go to Settings > Update & Security > Activation and enter your Windows 10 product key. 

    2. If your product key is not accepted 

    • Ensure the key matches the correct edition (Home vs Pro). 
    • If the key is invalid or for a different version, you may need to purchase a valid key from the Microsoft Store or an authorized reseller. 

    3. If you are using an OEM version 

    • OEM keys are tied to the original hardware and edition. 
    • You can upgrade from Windows 10 Home OEM to Pro by entering a Pro key in Settings, but you cannot transfer OEM keys to another device. 

    4. If you expected a free upgrade 

    • The free upgrade program from Windows 7 to Windows 10 has ended. 
    • You will need to purchase a Windows 10 license to proceed. 

    5. If you encounter activation errors 

    • Try running the activation troubleshooter: 

    Settings > Update & Security > Activation > Troubleshoot 

    • Or use the command: slmgr.vbs /ipk <YourProductKey> 

    If you need detailed steps for any of these solutions, please let me know, I’ll be happy to provide them. 

    Thank you for your patience and understanding. I'm here to make sure your upgrade process is as smooth as possible.
