What is a Comprehensive media kit versus a Subscription Media Kit?
A Comprehensive Media Kit is a one-time purchase of a complete media “welcome kit” for a given MSDN Subscription level; it is intended for new subscribers and does not include subsequent media updates. Subscription Media Kits comprise regular media updates for existing subscribers and are billed to the number of months remaining on your agreement. Comprehensive and Subscription Media Kits are available through EA, Select, and Open Value. Customers of these programs have the option of purchasing just a Subscription media kit to maintain an existing media subscription; only purchasing Comprehensive kits when adding new users. Additional Media Kits for Open License customers comprise both a complete comprehensive welcome kit and monthly subscription shipments; new and renewing subscribers should order the same kit.
