The following explains how to improve NVMe performance on Windows Server 2025 or Windows 11 by enabling Native NVMe.

  1. Download and install the latest Windows updates on Windows Server 2025 or Windows 11.
  2. For Windows Server 2025, this feature becomes available after installing update KB5072033 (x64).
  3. This Microsoft update is designed to improve NVMe performance and reduce CPU load when working with NVMe drives.
  4. To enable this feature, run the registry command below, or copy and paste it into the Command Prompt.
    reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 1853569164 /t REG_DWORD /d 1 /f
    reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 156965516 /t REG_DWORD /d 1 /f
    reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 735209102 /t REG_DWORD /d 1 /f
  5. After enabling the feature, reboot the server PC to apply the changes.
  6. To verify that Native NVMe is enabled, open Device Manager and check under Storage Controllers; your NVMe device should be listed there. (Figure 1)

  2. Tests in a local environment also show higher random 4K read and write speeds. Random 4K performance is critical for diskless systems.
  3. Native NVME disabled (Figure 2)
