Check on official site wich key you must press during pc bootup, for opening the service menu. There you'll find the Restore tool.
But you can revert directly inside Windows 10 -> Start -> Settings -> Restore -> Previous Windows

But is very strange you cannot activarte. You can use every genuine Windows key you got, even a Xp key
