: It creates a virtual registry and file system that prevents conflicts between the application and the underlying operating system. Legacy Support
Unlike full machine virtualization (like VMware Workstation) or OS-level containers (like Docker), ThinApp operates at the user-mode layer . It intercepts file system and registry calls from the application and redirects them to a sandboxed environment. The result? Applications run as if they are natively installed, but they leave no footprint on the underlying operating system.
