If you were asked for key when trying to do the upgrade from install media, you used the wrong install media. What version of 10 you get, Home or Pro, depends on what version of Windows you upgrade from. You need 7 Pro or better, or 8.1 Pro to get 10 Pro. Otherwise its 10 Home. Example, if you have 7 Home Premium and try to upgrade to 10 Pro, it will ask for a key. Do the upgrade to 10 Home and it won't ask for a key. Once you do the free upgrade and activate Windows 10 your hardware ID is stored on the activation server along with which version of Windows 10 you got, Home or Pro.. You don't need a key if you install the same version you got via the free upgrade, you us the skip option.
