A new Windows version for multiple users was spotted last month, and now we know what it's for: Windows Virtual Desktop (WVD) is a new service providing multi-user remote desktop and VDI in the Azure cloud.

WVD combines three things. Using the new Windows 10 version, WVD can be used to provide remote desktop sessions with multiple users remotely logged in to the same Windows 10 virtual machine (or, alternatively, a Windows Server virtual machine). This can provide both remoting of a full desktop session and of individual applications, serving as a replacement for the RemoteApp service that Microsoft cancelled last year. The service also supports full VDI, with remote users each having their own single-user virtual machine while both persistent and non-persistent VMs are supported. This is supported both with Windows 10 and with Windows 7.
