How to run Win 10 Pro after buying Win 11 Pro license.
That is, I understand one can use a Windows 11 Pro key to install and activate the Windows 10 Pro installation, knowing that the key and the activation are not licenses but instead just enable the product.
The license is the COA sticker and as long as the unit has a Windows 11 Pro COA sticker, one has the rights to install Windows 10 Pro.
