User State Virtualization separates the user's data and settings from the physical device and replicates it centrally. Microsoft recommends that you start first with User State and Application Virtualization if you plan to incorporate virtualization into your desktop strategy. It's because once these layers are configured they can be applied to users running traditional PCs or laptops, users running Remote Desktop Services (RDS) or users running their desktops via Virtual Desktop Infrastructure (VDI). Let's take a closer look.
USV enables user mobility and fast recovery of data in the event a device is lost. Because the data is stored centrally, delivered on demand when the user logs in, and synchronized based on policy configuration, users get their personalized Windows experience immediately regardless of which PC the login into. If they lose their primary device, IT delivers a machine with a more generic Windows 7 image, without needing to copy any data -- enabling them to recover and be productive faster.
Enable USV. Using Microsoft's Folder Redirection, Roaming User Profiles and Offline folders, IT can deliver the user's personalized Windows experience to any Windows Desktop they log into, physical or virtual.
