The default download of Windows is Pro (This is a parallels install). Could that be the issue if I bought a Home license? If so how do I download Home instead of Pro? If not I've entered that code 4 or 5 times and It just doesn't work

Windows for home | Windows 10 | Licensing and activation

    Hi,

    As QA Assist said, the Windows 10 Home Product key cannot activate Pro.

    During the time of Windows install you should be asked about which version you want to install. Were you not asked?

    See the section Install Windows 11 or other Windows manually here:

    I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!

    Yes. If Windows Pro is installed, a Windows Home product key will not activate it because the installed edition must match the license.

    For Windows 10, if a digital license or product key is for Home but Pro is installed, Windows needs to be reinstalled as Windows 10 Home. Microsoft states that when Home is licensed but Pro is installed, the fix is to install Windows 10 Home using the media creation tool, then skip entering a key during setup if there is already a digital license, or enter the Home key during setup if using a new product key.

    Steps:

    1. Check the installed edition:
      • Go to Start > Settings > Update & Security > Activation.
      • Confirm whether the device shows Windows 10 Pro or Windows 10 Home.
    2. If Windows 10 Pro is installed and the purchased key is Windows Home:
      • Reinstall Windows 10 Home.
      • Use the Windows 10 media creation tool page.
      • During Windows 10 Home setup, enter the Home product key when prompted, or skip the key entry if a Home digital license already exists.
    3. If the device already has a digital license for Windows 10 Home but is currently on Pro:
      • Install Windows 10 Home and Windows should activate automatically after installation completes.
    4. If the device was previously activated and was repaired, rebuilt, or had a different edition installed:
      • Reinstall the original version of Windows that was previously activated, then re-enter the original product key.

    Important:

    • A first-time installation of an edition that was never previously activated on that device requires a valid product key for that edition.
    • Installing Windows 10 Pro on a device that previously had Windows 10 Home requires a valid Windows 10 Pro product key.
