User environment virtualization is the abstraction of personalized computer settings from an end user's operating system and applications.
User environment virtualization software allows desktop and application virtualization users to keep personalized settings -- such as desktop wallpaper and browser bookmarks -- even though the operating system and software applications come from a standardized template or golden image shared by everyone. These settings can follow users from session to session and from one physical machine to another.
User environment virtualization is an extension of traditional profile management tools that desktop virtualization platform vendors and third-party software providers have previously offered. For example, Microsoft's User Experience Virtualization (UE-V) technology is different than its earlier Roaming Profiles feature. UE-V stores personal settings on a file server and delivers them via an agent that monitors for and responds to settings changes.
