    Windows activation is tied to both the license type and the device/hardware it was originally activated on. The context provides these key points that apply to this scenario:

    1. A Windows license is associated with device hardware. Significant hardware changes (or moving to a completely different device) can prevent Windows from locating a matching license when the device restarts or when installed elsewhere.

      “A Windows license is associated with your device hardware. Significant hardware changes, like replacing the motherboard, can prevent Windows from locating a matching license when the device restarts.”

      This same principle applies when moving from an Intel/Boot Camp installation on one MacBook to a Windows 11 Pro ARM VM on a different MacBook (M4). The new ARM VM is seen as a different device.
    2. If Windows came preinstalled (OEM) on the original device, that license cannot be transferred to a new device. If it was a full Retail license, it is transferable in principle, but:
      • The context shows that digital licenses and activation after hardware change are handled via the Activation troubleshooter and/or direct Microsoft support.
      • For digital licenses sourced from older upgrade paths, the ability to reuse them on new devices has been restricted:

      “If you had the original licence upgraded via a free upgrade those licences are not allowed to be used for Windows 11 anymore. You were able to use it previously when changing devices but that loophole has been closed.”

    3. For hardware changes or moving a Retail license, the supported paths in the context are:
      • Use the Activation troubleshooter and the “reactivate after a hardware change” path if the same Microsoft account and digital license are still correctly associated with the device.
      • If that fails or the device/license association is broken, contact Microsoft Support to see if they can manually reactivate or re-bind the license:

      “Because this forum is just a user to user forum, you will need to contact Microsoft directly, they may be able to find the digital licence on your account and re-activate Windows for you.”

      “I was able to get in contact with support who were able to reactive my license for me.”

    4. The context does not provide any supported method to transfer a Windows 10 Pro x64 Boot Camp license directly to a Windows 11 Pro ARM VM on a different MacBook. It only documents:
      • Reactivation on the same device after hardware change.
      • General reasons why activation can fail (missing key/digital license, wrong edition, overused key, volume licensing issues, etc.).
      • That some older upgrade-based digital licenses can no longer be reused for Windows 11 on new hardware.

    Given this, the supported options from the context are:

    1. Verify edition and activation method
      • Ensure Windows 11 Pro ARM in the VM matches the license edition (Pro vs Home). If the product key is for a different edition, activation will fail:

        “The product key used on this device isn’t compatible with this edition of Windows. You may need to contact the store or company where you purchased Windows, enter a different product key, or visit the Microsoft Store to buy a genuine copy of Windows.”

    2. Try activation with an existing product key (if available)
      • In Windows 11 Pro ARM VM:
        • Go to Start > Settings > System > Activation.
        • Select Change product key and enter the 25-character Windows 10 Pro Retail key if one exists.
      • If activation still fails with errors like 0x803F7001 (no valid license found), follow the documented guidance for that error:

        “If you encounter error code 0x803F7001, it indicates that a valid Windows 11 license could not be found… If you don’t have a valid product key, select Go to Microsoft Store, and follow the instructions to buy a digital license for Windows.”

    3. If the license is only a digital license (no key) and tied to the old device
      • The context indicates that when the digital license cannot be found or transferred via the troubleshooter, the only supported path is to contact Microsoft Support. In multiple similar cases, moderators state that only support can potentially locate and reassign the digital license:

        “You will need to contact Microsoft directly, they may be able to find the digital licence on your account and re-activate Windows for you.”

      • If support cannot or will not transfer it (for example, because it originated from an old free upgrade or is otherwise not eligible), the documented alternative is to purchase a new license from the Microsoft Store within the VM.
    4. When activation cannot be transferred
      • If the license originated from a free upgrade path or is otherwise blocked from reuse on Windows 11/new hardware, the context explicitly notes that reuse is no longer allowed and that the outcome will not change even if the old device is removed from the account:

        “You were able to use it previously when changing devices but that loophole has been closed.”

      • In that case, the only supported resolution in the documentation is to obtain a new, valid Windows 11 Pro license for the ARM VM via Settings > System > Activation > Go to Microsoft Store.

    Summary based on the context:

    • There is no documented, guaranteed way in the provided material to transfer a Windows 10 Pro Boot Camp license on an Intel MacBook directly to a Windows 11 Pro ARM VM on a different MacBook.
    • If a transferable Retail key exists, it can be tried via Change product key in the VM.
    • If activation still fails or the license is only a digital license tied to the old device or an old upgrade, the documented options are to contact Microsoft Support to attempt manual reactivation, or purchase a new Windows 11 Pro license for the ARM VM.
