Windows 11 Pro Upgrade from Windows 10 Pro Edition

No but after it installed the malfunctioning Windows 11 upgrade it was listed as Windows 11 Pro. Microsoft Windows support advised I reinstall Windows 10 Pro and said that Windows 11 is really only meant for new PC's that come with it preinstalled. MSI website doesn't list my 2020 GT76 Titan dt-039 notebook on their Windows 11 upgrade eligibility list so I guess that's why the Windows 11 Pro upgrade failed. I suggest being careful with trying the Windows 11 upgrade despite it stating my notebook was capable of running Windows 11 it was wrong. Luckily I have the original Windows 10 Pro USB Flash drive because the Windows 11 Pro upgrade was so incomplete I had no way of reverting notebook back to Windows 10 without reinstalling from a USB Flash.

 

Deactivating and Reactivating Microsoft Windows 11 Pro

My previous laptop just died on me and so I recently switched to a new laptop. On my previous laptop I had Microsoft Windows 11 Pro and on this one I have Microsoft Windows 11 Home. I was wondering if there was a way I could deactivate it on my previous laptop and then reactivate it on my new laptop. I still have the product key but it won't let me upgrade. I have attached the error message I keep receiving.

 

Free upgrade from Windows 11 Home to 11 Pro using 10 Pro retail license

My current computer has an activated Windows 10 Pro retail license. I'm planning to replace my current computer by buying a new computer that comes preinstalled with Windows 11 Home, and then I understand I can use my 10 Pro license to upgrade to 11 Pro for free.

What's the most straightforward way of accomplishing this? The obvious approach that comes to mind involves two steps:

1. Reinstall Windows 10 Pro on new computer and activate with my existing retail license.
   
2. Upgrade new computer to 11 Pro for free through the settings.
   

Is there a simpler way of doing this without having to reinstall Windows 10? For example, would it be possible to somehow "trade in" my Windows 10 Pro license for 11 Pro? I'm fairly new to Windows licensing and am just trying to understand what is possible/best practice, with minimal effort.
