Microsoft blocks registry trick that unlocked performance-boosting native NVMe driver on Windows 11 — workarounds still exist to enable support, however

Microsoft has disabled a registry modification that allowed Windows 11 users to activate native NVMe support. This change was noted in the latest Insider builds of Windows 11. The registry trick had previously improved random write performance by up to 85% and enhanced random I/O across various drives and CPUs. However, it caused compatibility issues with third-party SSD management tools and could trigger recovery prompts from BitLocker. Users can still enable native NVMe support using a third-party utility called ViVeTool, which requires an elevated command prompt and a system reboot. The timeline for official native NVMe support in Windows 11 versions 25H2 and 26H2 is uncertain.

Windows Server 2025 Native NVMe: Storage Stack Overhaul and Benchmark Results

On December 15, 2025, Microsoft announced native NVMe support in Windows Server 2025, marking a significant evolution in data management and access. The new architecture replaces Disk.sys with NVMeDisk.sys, allowing direct communication from the filesystem to hardware via StorMQ, eliminating latency and enhancing performance. Testing revealed increased read speeds, particularly in random 4K and 64K benchmarks, with significant reductions in average read latency and lower CPU usage during sequential operations. Write operations showed modest improvements. A registry modification is required to enable this feature, and caution is advised due to potential complications with NVMe drives when deduplication is enabled.

Someone released the Windows 7 and Vista ISOs with all their updates applied

Unofficial ISOs for Windows 7 and Vista have been released, containing all updates applied through January 2026. The Windows 7 ISO includes essential drivers like USB 3.x and NVMe support, while the Vista version has updates but lacks additional drivers. Experts caution against using these unsupported operating systems on internet-connected devices, despite their appeal to users nostalgic for older Microsoft interfaces.

Native NVMe support in Windows Server 2025 promises dramatic speed gains

Microsoft has introduced native NVMe support in Windows Server 2025, enhancing the performance of modern NVMe devices, including PCIe Gen5 SSDs and high-end Host Bus Adapters (HBAs). This feature eliminates the translation layers that previously routed NVMe I/O through SCSI, resulting in reduced processing overhead and latency. Testing shows that Windows Server 2025 can achieve up to 80% higher 4K random read IOPS and approximately 45% fewer CPU cycles per I/O compared to Windows Server 2022. The enhancements benefit enterprise applications such as SQL Server, OLTP workloads, and virtualization environments using Hyper-V, as well as analytics and AI/ML workloads. To utilize native NVMe, system administrators must use the in-box Windows NVMe driver, and the feature requires an opt-in process with the latest cumulative update and registry key or Group Policy configuration. Organizations should validate the implementation to assess its impact on their production environments.
