Found this thread on reddit on reddit. Apparently this registry tweak in powershell on 24H2/25H2 gives a little boost to read and random write speeds:
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 1176759950 /t REG_DWORD /d 1 /f
Anyone want to try?

Edit by Fernando: Thread title customized
I did try this morning, but im not really onto finding the performance, and one thing i notice is that the windows startup apps that usually takes a while to load, loads faster. That regedit, is for windows server, for client, use these;
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 1853569164 /t REG_DWORD /d 1 /f (UxAccOptimization, required)
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 156965516 /t REG_DWORD /d 1 /f (Standalone_Future, required)
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 1409234060 /t REG_DWORD /d 1 /f (NativeNVMeStackEnableForClientOS)
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 735209102 /t REG_DWORD /d 1 /f (NativeNVMeStackForGeClient, for germanium build, instead server)
Results:
So its worth a try. Confused about the apprentices if required (Standalone_Future, required) for example?
Thanks
The forum i’ve seen about this subject said it is required, but if you’re willing, you can try without using the Standalone_Future regedit and see if it would activate the native nvme or not.
Meanwhile I have done some own tests with 2 different AMD Chipset PCs:
a) an ASRock X570 Pro4 PC with 2 NVMe SSDs (1TB Samsung 990 Pro + 2TB WD Black) and
b) a modern GEEKOM-A7 Mini-PC with 1 NVMe SSD (2TB Acer N5000).
Onto both PCs I did a fresh install of the currently latest Win11 Pro “Windows Insider” version (Build 28020.1362):
The GEEKOM-A7 Mini-PC had the new “Native NVMe Disk Drive Support” from scratch (without the need of doing any Registry tweaks). Here is the screenshot of its Device Manager content:
The Device Manager of the AMD X570 chipset PC didn’t show the “Storage Media/Disks” section at all, not even after having run the recommended Registry tweaks. Both attached NVMe SSDs were still listed within the “Disk Drives” section:
Bad consequence: The data, which I had stored onto my removable Samsung SCSI SSD while running any of my 2 AMD PCs were not visible on the other!
Other users have already reported about other severe disadvantages after having enabled the “Native NVMe Disk Drive Support”.
Example:
SSD tools (like Samsung Magician) do not detect the in-use NVMe SSD anymore or list them twice.
My consequence:
Before I will do any further tests regarding this new NVMe feature, I am waiting for a solution of the already evident problems.
In this article I’ve read online similar to many others there is apparently a hidden driver in Windows 25h2 which when adding the properly set regtweaks to the OS will replace the use of old SCSI disk.sys with nvmedisk.sys
reg add HKLM\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 735209102 /t REG_DWORD /d 1 /f
reg add HKLM\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 1853569164 /t REG_DWORD /d 1 /f
reg add HKLM\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 156965516 /t REG_DWORD /d 1 /f

If done correctly a noticeable speed boost can be acheived
You also know it’s truly working when you see your disk move in devmgmt from Disk Drives to Storage Disks as shown below -
My question is, can this nvmedisk.sys driver and associated regkeys in the article be backported to earlier versions of windows say for instance 22h2?
Thanks in advanced!
The timing of this and the fact there is little to no improvement, tells me this is a huge risk.
While all companies are in holidays…. could cause vulnerabilities.
Test on a potato legacy-BIOS PC and $20 NVMe SSD by SiliconPower
The test system: LGA 1156 i7 870, SPCC M.2 NVMe SSD @ PCIe 2.0 x1
Before:
After:
Boost is really nice (75% and 61% for RND tests) for a three lines of powershell and reboot. Free performance is never bad.
But now cons: boot time of Windows 11 with that tweak and 80% free disk space is ~36 s which is exactly same as Windows 10 with 95% occupied disk space of the same $20 SSD. And the whole Windows 11 system feels much more clanky and slowish than Windows 10. Also Windows 10 was ready to go after desktop appeared but Windows 11 have small lag in displaying taskbar and icons. In my opinion I’ve got scammed by thinking “THAT TIME IS NOW!”. But if you have not a potato PC which can’t handle Windows 11 then it’s totally worth it if you have standard NVMe (which is actually SCSI lol) driver by Microsoft and not one provided from vendor of your SSD.
If this patch will be available for Windows 10 it’s worth going back and applying tweak (instead of moving to Linux which I hope have native NVMe support).
Path to device now:
NVME\NVMEDISK&VEN_1E4B&SUBSYS_.........
And I clearly remember how it was SCSI earlier.
So the main advice I think is wait untill someone will port this gold to Windows 10!
Today I have done a clean install of Win11 Pro v25H2 (Build 26200.7462) onto my AMD-PC with an X570 Chipset and was able to get the “Native NVMe Disk Drive Support” working with this configuration by executing the related 3 Registry commands.
These were the connected PCIe 4.0 NVMe SSDs
(both using the MS in-box NVMe Storage Controller driver named stornvme.sys):
This is what the Device Manager showed:
Benchmark Results:
Here are the benchmark results I got before (left/upper Pic) and after (right/lower Pic) having enabled the “Native NVMe Disk Drive Support”:
a) 1 TB Samsung 990 Pro SSD as System Drive C
b) 2 TB WD_Black SN850X SSD as Storage Drive D
Evaluation:
Contrary to my previous test with a Geekom AMD Mini-PC the “Native NVMe Disk Drive Support” gave my X570 chipset AMD-PC a clear boost of the 4K and 4K-64 Thread performance while reading and writing.
The Sequential Read and Write numbers were not affected at all by the driver change.
Nice numbers “Boss”…cheers.
Are these tweaks “Direct Storage” compatible?
