With these additional features enabled, I mange to get it running on Windows 11 (disk showing up under Storage Disks as NVMe) - but I can't measure any improvement, in fact I only get worse numbers after the change.
The article only talks about WS2025, do any of you know if it actually is suppose to work on clients?

Additional keys for Windows 11 - but I don't see any performance gains, so I might not work on clients at all - do you see a difference?

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

You need to register the class id's in these locations or safemode will be broken

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\{75416E63-5912-4DFA-AE8F-3EFACCAFFB14}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\{75416E63-5912-4DFA-AE8F-3EFACCAFFB14}

They aren't present on server either......

    Is this true for Windows Server as well? Anyone tested WinRE after the change? 

    I can check that, just looking for other references.

    Confirmed.  This is true on all test systems I've tried.  CoPilot came up with a script that resolved it.  I imagine a future state where a wizard or enablement package automates the process once enough field testing identifies more of these scenarios.

    They are only related to SafeBoot right? and not the actual performance gain it self?
    Or am I missing something here?
