Microsoft has closed a popular registry hack that allowed Windows 11 users to activate a native NVMe driver delivering significant performance boosts. Initially hidden and disabled by default, the native NVMe driver (nvmedisk.sys)-first introduced with Windows Server 2022-offers up to 80% better input/output operations per second (IOPS) and reduces CPU usage by 45% under heavy data loads by bypassing the older SCSI translation layer.
Enthusiasts discovered that tweaking certain registry keys could trigger the native driver on Windows 11 PC builds, providing noticeable gains in random I/O speeds and write throughput. Benchmarks from various sources reported up to 65% faster 4K random reads and considerable write improvements. However, this workaround was far from flawless. Compatibility issues arose with third-party SSD utilities like Samsung Magician and Western Digital Dashboard, and Microsoft’s BitLocker encryption tool sometimes prompted recovery mode following the switch.
Now Microsoft has stepped in to block the registry hack in recent Windows 11 Insider Preview versions, effectively shutting down this unofficial path to faster NVMe performance. The native driver remains inactive by default on consumer Windows 11 editions 25H2 and 26H2, with no confirmed schedule for official rollout. For users willing to take more technical risks, the ViVeTool utility still enables the native driver via feature IDs 60786016 and 48433719, though it also requires handling BitLocker’s quirks and performing system reboots.
This move highlights Microsoft’s cautious approach to rolling out deep system performance features. While the native NVMe driver represents a real advancement, broad compatibility and stability concerns-especially around encryption and storage management tools-mean the company prefers a controlled, vetted deployment over community-driven hacks. Until then, enthusiasts craving the speed gains will either wait for official support or tinker with unofficial tools while temporarily suspending BitLocker protections.
