This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

To legally register an install of Windows 7, you'll need to use up a key, even in a virtual machine such as virtualbox. – jakev Sep 11 '12 at 22:44

Yes, it will use a key since you need one licence/key per installation. Not one per computer.
