There is information on the Hyper-V Server 2019 homepage suggesting that it can be used for free, and VM companies are supplying this product for free.
However, we understand that this product requires purchasing a valid Windows Server license to use it legally. We would like to confirm with Microsoft whether this product can be officially used by businesses and institutions without issues.
