What is the new Windows 10 multi-session?

Azure Virtual Desktop enables the capability of Windows 10 Enterprise multi-session available only in Azure. This allows full fidelity access to a Windows 10 experience—including the user experience, Office ProPlus support, Microsoft Edge, Cortona, per user search index, and access to the Microsoft store—whilst taking advantage of the cost efficiency of shared compute resources previously only available with server-based virtualisation.
