If it has never been activated did you buy a licence, if yes where from.
To check the current licence (if any) open Command prompt (Admin) and enter slmgr /dlv [press return] and post a screenshot of the result.

Is this a device with Windows pre-installed or you purchase the Windows?
Is there any error message?
