A new feature introduced in SQL Server 2012 setup is “Product Update”.
Product Update searches for the latest product updates and integrates it with the main product installation.It can search for the latest or applicable updates in Microsoft Update,Windows Server Update Services (WSUS), a local folder or a network share. Product Update can pull in a cumulative update, service pack, or service pack plus cumulative update. And once update is found, it downloads it and integrates with current SQL Server installation or setup process.
