- A consistent processor-based licensing model that covers up to two physical processors on a server.
Windows Server 2012 Essentials edition and Windows Server 2012 Foundation edition remain unchanged.
- Server-based licensing model – Foundation is for single processor servers and Essentials is for either one or two processor servers.
- CALs not required for access – Foundation comes with 15 user accounts and Essentials comes with 25 user accounts.
Determining the number of licenses for Datacenter and Standard editions
Each license covers up to two physical processors on a single server. The minimum number of licenses required for each server is determined by the number of physical processors. For Standard edition you can add more virtual instances by assigning additional licenses to the server (two incremental virtual instances are added per license).
