appcontainer support

AppContainer support in PowerShell 7.6.2 enables hosting PowerShell processes within Windows AppContainers, providing an additional security boundary for script execution. This feature, introduced in the May 2026 servicing update, allows administrators to run PowerShell in a sandboxed environment with restricted access to system resources. The implementation aligns with Windows privacy settings and is part of the Long-Term Support branch's ongoing enhancements. For users managing secure automation or multi-tenant environments, AppContainer support offers a way to isolate PowerShell sessions without requiring full virtualization. The feature is available in PowerShell 7.6.2 and later servicing updates.
