Microsoft's approach to Windows security and hardware lifecycle management has taken some interesting turns recently. While the company is pushing users to upgrade from Windows 10 to Windows 11-compatible hardware, it's simultaneously deprecating certain security features in older Windows 11 versions. These contradictory messages highlight Microsoft's evolving strategy for its operating system ecosystem.

Microsoft Quietly Deprecates VBS Enclaves Security Feature
Microsoft has recently added Virtualization-based Security (VBS) enclaves to its list of deprecated Windows features. This security enhancement, which was introduced just nine months ago in July 2024, is being phased out for Windows 11 version 23H2 and earlier, as well as Windows Server 2022 and earlier releases. Interestingly, the feature will continue to be supported in Windows Server 2025 and newer versions. VBS enclaves were designed to create secure memory spaces with higher privileges than the operating system itself, allowing developers to protect specific parts of their applications through a virtual machine running atop Microsoft's Hyper-V hypervisor. The decision to remove this relatively new security feature raises questions about Microsoft's development priorities and the potential impact on enterprise customers who may have implemented it.
Windows 10 PCs Still Have Life After Support Ends
In contrast to its push for hardware upgrades, Microsoft's suggestion that users should trade in Windows 10 PCs that can't upgrade to Windows 11 has been met with alternative perspectives. There are numerous productive ways to extend the life of older hardware beyond Microsoft's support window. Installing Linux distributions like Ubuntu or Pop! OS can provide years of additional support for aging hardware with relatively low system requirements. Other repurposing options include creating retro gaming machines with Emulation Station, setting up media servers with Plex or Jellyfin, hosting game servers for titles like Minecraft, powering smart home systems with Home Assistant, building network-attached storage (NAS) solutions, or even establishing comprehensive home labs using platforms like Proxmox or Docker.
Accelerated Development Cycle May Explain Feature Deprecation
Microsoft's decision to deprecate VBS enclaves in Windows 11 23H2 may be connected to the company's accelerated development cycle, which now delivers major releases annually alongside frequent monthly updates. According to Microsoft's documentation, VBS enclaves require Windows 11 Build 26100.2314 or newer, suggesting the company may be deliberately excluding older builds to avoid compatibility and reliability issues. While Microsoft typically continues to support deprecated features until they're completely removed, the timing is notable as Windows 11 23H2 support ends in November 2025. Enterprise customers still relying on this security feature could potentially face disruptions if they don't upgrade to newer Windows versions.
Balancing Security, Innovation, and Hardware Lifecycles
These developments reflect Microsoft's complex balancing act between pushing hardware upgrades, maintaining security, and managing feature development across multiple Windows versions. On one hand, the company is encouraging users to discard perfectly functional hardware that doesn't meet Windows 11 requirements. On the other hand, it's removing relatively new security features from older but still-supported Windows 11 versions. This approach creates challenges for both individual users and enterprise customers trying to plan their technology roadmaps. For users unwilling to discard functional hardware, the various repurposing options demonstrate that older PCs can continue to provide value long after Microsoft's official support ends, whether through alternative operating systems or specialized use cases.
