Once Visio is associated with your Microsoft account, you no longer need the product key. It will always be linked to your account and you can re-download the app or manage your license from account.microsoft.com.
Alternately, in the upper right hand corner just below the application minimize, restore and close buttons you'll find the document minimize, restore and close. Choose restore, and you can manipulate the windows inside the main visio app.
