Hello! I want to change Network adapter's power managament settings. I want to check 3 checkboxes. I searched this on google but i couldn't successfull. I changed HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E972-E325-11CE-BFC1-08002bE10318}\DeviceNumber on regedit but it's not applying. This regedit value is true but i think it's readonly. How can i set 3 checkboxes checked and save? Thanks a lot!

It is done with WmiSetSingleInstance I tested on Windows 10 with similar code I had posted at Disabling auto-suspend (of an USB hub) using c++ by replacing hdi = SetupDiGetClassDevs(&GUID_DEVCLASS_NET, NULL, NULL, DIGCF_PRESENT); the test on lpszCompDescription by a given network adapter GUIDs for 2 other check boxes : DEFINE_GUID(GUID_POWER_DEVICE_WAKE_ENABLE, 0xa9546a82L, 0xfeb0, 0x11d0, 0xbd, 0x26, 0x00, 0xaa, 0x00, 0xb7, 0xb3, 0x2a); DEFINE_GUID(GUID_POWER_DEVICE_WAKE_ON_MAGIC_PACKET_ONLY, 0xa14f1c97L, 0x8839, 0x4f8a, 0x99, 0x96, 0xa2, 0x89, 0x96, 0xeb, 0xbf, 0x1d);

Hello, Thank you for answer.
But i couldn't succesful :(

What i tried 1:
GUID RealtekGUID= {};
CLSIDFromString(L"{4D36E972-E325-11CE-BFC1-08002bE10318}", &RealtekGUID);
hdi = SetupDiGetClassDevs(&RealtekGUID, NULL, NULL, DIGCF_DEVICEINTERFACE | DIGCF_PRESENT); /* NOT entering while loop (SetupDiEnumDeviceInfo) */

What i tried 2:
WCHAR* DATA_wmiSetSingleInstanceW = (WCHAR*)"PCI\VEN_10EC&DEV_8125&SUBSYS_879B1043&REV_00\6&322AF77E&0&0020000A"; // pnp device id
GUID wmiGuid= {};
CLSIDFromString(L"{4D36E972-E325-11CE-BFC1-08002bE10318}", &wmiGuid);
int newvalue = 5;
nError = WmiOpenBlock((LPGUID)&wmiGuid, 0, &hWmiBlock);/* nError = 4200, hWmiBlock = 0 > [error code]ERROR_WMI_GUID_NOT_FOUND 4200 (0x1068)*/
auto hdi = WmiSetSingleInstance(hWmiBlock, DATA_wmiSetSingleInstanceW, NULL, sizeof(newvalue),&newvalue);

tried reverse engineering and pretty sure you said function is true but don't know how to call.

You did not follow what I wrote :

hdi = SetupDiGetClassDevs(&GUID_DEVCLASS_NET, NULL, NULL, DIGCF_PRESENT);

to enumerate network adapters.

The 2 other GUIDs are for WmiOpenBlock, like :

nError = WmiOpenBlock((LPGUID)&GUID_POWER_DEVICE_WAKE_ON_MAGIC_PACKET_ONLY, 0, &hWmiBlock);

II called 3 times the block of code WmiOpenBlock/.../WmiSetSingleInstance (you can do a function...)
with the 3 GUIDS GUID_POWER_DEVICE_ENABLE, GUID_POWER_DEVICE_WAKE_ENABLE, GUID_POWER_DEVICE_WAKE_ON_MAGIC_PACKET_ONLY
to test the 3 check boxes

Thank you very much finally we did it ! :)

Unfortunately link to "Disabling auto-suspend (of an USB hub) using c++" is no longer working.
