    Hello,

    What type of license do you have? Upgrade license from Microsoft, or third party license key (5x5)?

    What error did you get if any?

    This is the standard method for most cases -

    You can go to Settings > System > Activation > Change product key

    Disconnect internet, and disable any third party antivirus, key in the generic key instead: VK7JG-NPHTM-C97JM-9MPGT-3V66T

    That should get you to Pro. Once restarted, you can connect back to the internet. If you have a digital Microsoft license, sign into your account, or go to Settings > System > Activation, run the troubleshooter, choose the hardware change option. When it asks you where it is installed on right now, you should choose the old device name. Then click on Activate button. And on the next screen when it asks you where to transfer it to, choose your new device name. See if that works.

    If you have third party 5x5 key, then go to Change product key again and enter it.

    If for any reason this doesn't work, please provide more information/context, such as answers to the questions I asked above.. and is this a reinstall or first time upgrading?

    Use these steps and checks to resolve Windows 11 Home → Windows 11 Pro upgrade failures.

    1. Verify edition and activation first
    2. Open Start > Settings > System > Activation (or use: Open System > Activation).
    3. At the top of the page, confirm the edition shows Windows 11 Home.
    4. Under Activation state, confirm Windows is activated. If it is not activated, complete activation first using the guidance in Activate Windows before attempting any edition upgrade.

    If Windows 11 Home is not activated, the Pro upgrade will fail until activation is completed.

    1. Upgrade path when a Windows 11 Pro key is available

    If there is a valid Windows 11 Pro product key:

    1. Go to Settings > System > Activation.
    2. Next to Change product key, select Change.
    3. If a User Account Control prompt appears, sign in with an administrator account and select Yes.
    4. Enter the 25‑character Windows 11 Pro product key.
    5. Select Next and follow the prompts to start the upgrade. The device will restart during the process.

    If this path fails, double‑check that the key is specifically for Windows 11 Pro (or a Pro‑eligible license) and that it is not blocked or already in use elsewhere.

    1. Upgrade path when no Pro key is available

    If there is no separate Pro product key, use the Microsoft Store upgrade flow:

    1. Open Settings > System > Activation.
    2. Expand Upgrade your edition of Windows.
    3. Under Upgrade in the Microsoft app, select Open Store.
    4. In the Microsoft Store app, sign in with a Microsoft account and purchase Windows 11 Pro.
    5. After purchase is confirmed, follow the on‑screen instructions to install Windows 11 Pro and restart the device.

    If the Store‑based upgrade fails, ensure the device is online, the Microsoft account is signed in correctly, and Windows 11 Home is activated.

    1. When the upgrade option is missing or appears to do nothing

    If Upgrade your edition of Windows does not appear under Settings > System > Activation:

    • The device might already be running Windows 11 Pro, or
    • Edition upgrade might not be available on that installation.

    To confirm, open Start > Settings > System > About and check Windows specifications to see the current edition.

    1. Surface devices (if this is a Surface)

    For Surface devices that shipped with Windows 11 Home:

    • The same upgrade mechanisms apply.
    • Either use the Upgrade to Windows 11 Pro button from the official Surface page (when viewed on that device), or:
      1. Open Settings > System > Activation.
      2. Select Open Store.
      3. Complete the purchase and restart.

    The Surface must also be running an activated copy of Windows 11 Home for the upgrade to succeed.

    If, after confirming activation and using the correct path (product key or Store), the upgrade still fails, note any specific error code shown during the process and use that code for targeted troubleshooting or when contacting Microsoft support.
