Bizarre OS: Microsoft usually deprecates options in Home windows, usually changing them with improved alternate options or streamlining improvement. That is why its choice to drop a comparatively new safety characteristic – one it promoted lower than a yr in the past – raises questions on how Home windows is evolving and which customers could be left behind.
Microsoft has quietly added one other entry to its ever-growing record of deprecated Home windows options. The corporate is phasing out Virtualization-based Safety (VBS) enclaves in Home windows 11 23H2 and earlier, in addition to Home windows Server 2022 and earlier releases. Nonetheless, help will proceed in Home windows Server 2025 and past.
The Redmond tech large introduced VBS enclaves in July 2024, touting them as a major step ahead for Home windows safety. The characteristic depends on Virtualization-Primarily based Safety (VBS), a core a part of Home windows 11 that runs the OS inside a safe digital machine atop Microsoft’s Hyper-V hypervisor.
Because of VBS enclaves, builders can now create software-based trusted execution environments inside host functions. In less complicated phrases, a VBS enclave is a safe reminiscence house with larger privileges than the working system, working in a digital machine atop Hyper-V. Utilizing Dynamic Hyperlink Library information, builders can shield particular components of their functions, which any Home windows program can load.
Microsoft described VBS enclaves as a significant enchancment in software program safety for virtualized Home windows cases. Nonetheless, the corporate is eradicating the characteristic from Home windows 11 23H2. Microsoft usually deprecates a characteristic as soon as it stops creating it alongside the remainder of the Home windows code, although the characteristic often continues to work till builders fully take away it.
A potential clarification for Microsoft phasing out VBS enclaves is Home windows 11’s accelerated improvement cycle, which now delivers new main releases yearly and frequent, typically disruptive month-to-month updates. In response to Microsoft’s documentation, VBS enclaves and Intel Software program Guard Extension APIs require Home windows 11 Construct 26100.2314 or newer. Microsoft could also be intentionally excluding older builds to keep away from compatibility and reliability points.
Microsoft ends help for Home windows 11 23H2 this November, however most customers will probably have upgraded to a more recent launch by then. If Microsoft removes VBS enclaves completely from 23H2, enterprise clients nonetheless counting on the characteristic may face disruptions.
