appcontainer isolation

AppContainer isolation is a Windows security feature that runs applications in a lightweight sandbox, limiting their access to system resources and data. On WindowsForum.com, discussions highlight its integration into Windows 11 Task Manager, where users can now see which processes are running inside an AppContainer. This visibility helps IT administrators and security-conscious users monitor app behavior and enforce least-privilege principles. The feature is particularly relevant for Copilot+ PCs and enterprise systems, as it enhances protection against malware and unauthorized data access. Threads also explore how AppContainer isolation works alongside other security mechanisms like Windows Defender Application Guard and virtualization-based security.
