What Does Microsoft Volume Licensing Mean?
Microsoft Volume Licensing is a service offered by Microsoft for organizations that require multiple licenses, but not the software media, packaging and documentation supplied with the full packaged product (FPP). The advantages of Microsoft Volume Licensing include lower price per installation, two- or three-year license agreements and product use rights.

Starting with Microsoft Vista and later Windows OSs, VLKs were replaced with multiple activation keys or key management server keys.
