Windows 10: Can I reinstall Windows 10 Pro on machine that is installed with Windows 11 Pro ? not...

I have bought a dell desktop which came with windows 11 Home edition and my vendor upon my request he upgrade it from Home to Pro edition on Windows 11. But I need Windows 10 Pro only can I reinstall Windows 10 and use the same product key ? Its actually a OEM key will it work ?

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.

 

Clean Windows 10 (?PRO?) install

As far as I am aware there is no Windows 10 Pro version.
But I'd be happy to be wrong.

 

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.
