Windows 10: W10 pro not recognizing w 11 key

I got my driver wiped and need to install new windows. My system downgraded to windows 10 pro but won't accept w 11 key. My new build won't run w11. What to do? Is there a way to downgrade key to work on w10?

W10 Pro Key , use on new PC that comes with 11

I have a W10 Pro Key on a Dell Inspiron. Want to upgrade to a new XPS that comes with 11 Home.

I dont care about W11, and was thinking of installing W10 on new pc.


I love Bitlocker and thus really want Pro version

Is there a way to extract key from my OS?
If I sign in with my MS account will it know about the key to make transfer easy. It just shows the current device under my account with Windows Pro

 

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.
