Microsoft has announced the deprecation of Virtualization-based Security (VBS) enclaves, a feature introduced in July 2024, in Windows 11 23H2 and earlier versions, as well as in Windows Server 2022 and its predecessors. Support for VBS enclaves will continue in Windows Server 2025 and future versions. VBS enclaves were designed to create secure memory spaces using Microsoft's Hyper-V hypervisor, enhancing security for specific application components. The decision to phase out VBS enclaves may be influenced by the rapid development cycle of Windows 11. Users are expected to transition to newer releases as support for Windows 11 23H2 ends in November. Enterprise customers relying on VBS enclaves may face disruptions if the feature is completely removed.
