Activation issue: Hardware Change & Win 11 Upgrade

I had Windows 10 Pro on my old machine. Recently put in a new mobo and CPU. Ended up having to wipe my SSD and do a clean install because of some MBR to GPT boot drive issues.

Did a fresh Windows 10 install from USB drive and selected Windows 10 Home (Forgot I was using Windows 10 Pro previously) installed it, then immediately upgraded to Windows 11 Home.

Now Windows wont let me activate the OS since it shows my old machine with a Win 10 Pro license and says versions don't match. Is my only option to wipe everything again and reinstall Windows 10 Pro and then activate Windows at that point, then upgrade to Windows 11 Again?

Seems weird since its all tied to my microsoft account anyways.

Hi, I am Van. I'll be glad to assist you today.

If you have a valid Windows 11 Pro license key, you can directly upgrade a Windows 11 Home system to the Pro edition. Go to the activation settings, click the Change product key button, then enter your Windows 11 Pro license key. This process will perform an in-place upgrade to Windows 11 Pro. Alternatively, you can try the method below.

  1. Disconnect the internet connection on your PC.
  2. Reactivate Windows using the generic key below to upgrade to Windows 11 Pro.

Once you have upgraded to Windows 11 Pro, connect the internet on the PC and use your valid Windows 11 Pro product key to activate the operating system. Since you are activating on new hardware, please make sure your license is a retail type to avoid activation issues.

Please feel free to reach out if you require any further assistance. I'm here to help.
