Microsoft shuts down another Windows 11 registry hack — native NVMe SSD support is blocked but Insiders still have options

Microsoft has seemingly blocked a registry hack that allowed Windows 11 users to enable native NVMe storage support on their devices. The change was spotted by users in the "My Digital Life" forum in recent Windows 11 Insider builds (via Tom's Hardware).

For context, Microsoft announced that Windows Server 2025 would natively support NVMe drives in December, around 15 years after the storage technology launched.

According to those who managed to enable the feature on their PCs, it significantly improved performance of approximately 10% to 15%, citing lower latency and higher transfer speeds as it maximized read and write speeds on their solid-state drives while simultaneously reducing processor load.

Additionally, it reduced a few specific instances in which one or more apps performing storage-intensive tasks would cause Windows to freeze. The driver was introduced in Windows Server 2025, replacing the legacy SCSI translation layer used for NVMe SSDs with up to 80% higher IOPS and 45% lower CPU utilization under high I/O loads.

The driver binary had shipped with Windows 11, but it was disabled by default.

However, following Microsoft's Windows Server 2025 announcement, Windows enthusiasts managed to force Windows 11 to load the native driver by toggling specific registry entries. And while it delivered up to 85% higher random write performance in earlier benchmarks, it also shipped with some drawbacks.

Windows treats storage devices like older SCSI drives, so NVMe instructions are usually translated into SCSI equivalents first. In that, some third-party storage tools might either fail to recognize NVMe drives or mistakenly show them twice if the hack is enabled.

What's more, the registry trick also changes the disk ID, which can confuse apps like backup software and make it harder for them to detect the drive properly in the first place. As Tom's Hardware points out:

"Third-party SSD management tools like Samsung Magician and Western Digital Dashboard were not compatible with the new driver, and BitLocker could trigger recovery prompts after the driver swap."

While it remains unclear when Microsoft plans to ship native NVMe support for Windows 11 25H2 and 26H2 users with the nvmedisk.sys driver, it's still possible to enable it on your Windows 11 PC via "ViveTool" despite the OS-level block. (It's an open‑source app that allows users to enable or disable hidden features in Windows 10 and Windows 11.)

(As always, running third-party tools may potentially harm or render your device unusable. Proceed with caution!)

Microsoft’s decision to block the registry hack is a trade‑off between performance and stability. So, enthusiasts can still use ViVeTool to unlock native NVMe drivers, but that route might be risky for your average user. I'd argue that waiting for the official rollout in upcoming Windows 11 builds would be your safest bet.
