Decoupling the User/Kernel boundary in Windows is a monumental task and highly non-trivial, however, we have been working hard to stabilize this boundary across all of Windows to provide our customers the flexibility to run down-level containers. Starting with Windows 11 and Windows Server 2022 we are enabling the ability to run process-isolated WS2022 containers on Windows 11 hosts. We've done our best to capture the areas which break the boundary, but now want to open the feature to developers on Windows 11 for feedback. We are committed to enabling this experience for you, so please let us know when you experience issues.
