Windows 10: Upgraded Windows 11 Home to PRO and want to downgrade to 10 PRO

Is this even possible?

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.

 

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.

 

Is it free to upgrade from Windows 10 Pro to Windows 11 Pro?

Hello Microsoft Community and Support,

Right now I have Intel i7 NUC CPU. Windows 11 upgrade compatibility app tells me my device is eligible for Windows 11 upgrade.

I have Windows 10 Pro on that device.

Can someone clarify my doubts?

1. Is it free to upgrade from Windows 10 Pro to Windows 11 Pro?
   
2. Can I downgrade to Windows 10 Pro later?
   
3. Is there any equivalent of macOS TimeMachine backup on Windows so that I can fall back onto Windows 10 Pro if needed?
   

Much appreciate your response. Thank you.

Best!
