The Essentials edition does not support many advanced server features, however it does provide support of features like Hyper V, dynamic memory and hot add/remove RAM. Windows Server 2012 R2 Essentials edition can run a single instance of virtual machine on Hyper V, a feature that was not available in Windows Server 2012 Essentials (non-R2) edition. This single virtual machine instance can be Windows Server 2012 R2 Essential edition only, seriously limiting the virtualization options but allowing companies to begin exploring the benefits of the virtualization platform.

CALS are not required for this edition. User Limit is 25 users.
