In software licensing, a volume license key is the product key used when installing bulk licensed software, which allows a single product key to be used for multiple installations.
This type of licensing is typically for businesses, government agencies, and educational institutions. Volume license prices vary depending on the type, quantity, and subscription length. Examples of Microsoft programs available through volume licensing programs include Windows Vista, Windows 7 Enterprise, Windows 8 Enterprise, Windows Server 2008, Microsoft Office 2007, and many others.
