"Thinstall decouples applications from underlying operating systems, improving isolation and portability for applications across desktop environments. Thinstall’s unique, agentless approach to application virtualization enables the rapid, secure and cost effective delivery of software applications to desktops. Agentless application virtualization, pioneered by Thinstall, requires no pre-installed software on physical or virtual PC’s and no new deployment infrastructure or management tools. Thinstall’s architecture integrates into existing application management systems to deliver virtualized applications across a variety of operating system versions (NT, 2000, XP, Vista) and enables applications to move with users as needed."
