A Volume License Key (VLK) is a type of software license provided to organizations, institutions, or businesses that need to install and activate software on multiple computers. Instead of requiring a unique activation key for each device, a VLK allows for the installation and activation of software across many machines using a single key. This streamlines deployment and management, making it easier for IT departments to maintain software compliance and updates. VLKs are commonly used by companies, schools, and government agencies to efficiently manage large-scale software installations while adhering to licensing agreements.
