Purchased upgrade for my Windows 11 Home to Pro via Microsoft store online, order # 326732. But system shows Windows 11 Enterprise instead of Pro, and "activation status" shows "Not active." Error code: 0xC004C003. Troubleshoot did not help. I did not receive any product key with upgrade purchased. Can you please help?

    Hello,

    You are seeing Windows 11 Enterprise because your system registry is likely pointing to the Enterprise edition, perhaps from a previous installation or failed upgrade attempt. The error code indicates that your valid Windows 11 Pro license cannot be used to activate the Enterprise edition. We need to force the edition switch from Enterprise to Pro.

    Solution:

    1. Open Settings and navigate to System > Activation.
    2. Under Change product key, select Change.
    3. Enter the generic Windows 11 Pro product key: VK7JG-NPHTM-C97JM-9MPGT-3V66T
    4. Follow the prompts to complete the edition switch. The computer may restart several times.
    5. After the restarts, check Settings > System > Activation. The system should now show Windows 11 Pro.

    This sequence bypasses the incorrect Enterprise key and allows your Pro license to activate.

    It seems that you are experiencing an issue with your Windows 11 upgrade where it is showing as Windows 11 Enterprise instead of Windows 11 Pro, and the activation status is not active with error code 0xC004C003. This error typically indicates that the product key is either invalid or not available for the version you are trying to activate.

    Since you did not receive a product key with your upgrade purchase, it is important to verify the following:

    1. Check your Microsoft Store account: Sometimes, the product key may be available in your purchase history or confirmation email.
    2. Activation State: You can check the activation state by using the command prompt. Open a command prompt and run the command slmgr /dli to see the current activation status and product key information.
    3. Contact Microsoft Support: If you cannot find a product key and the system continues to show Windows 11 Enterprise, it would be best to contact Microsoft Support for assistance. They can help you resolve the activation issue and provide you with the necessary product key if applicable.

    Additionally, if you are using a device that was previously upgraded to Windows 11 Enterprise through a different means (like a volume license), it may need to be reverted to a compatible version before you can upgrade to Windows 11 Pro.

    Make sure to have your order number and any relevant details ready when you contact support for a smoother resolution process.
