DevCon UpdateDriverForPlugAndPlayDevicesW API logs Error in event viewer even on success.

Question

Hi,

I have recently noticed that if we use devcon.exe (C:\Program Files (x86)\Windows Kits\10\Tools\10.0.22621.0\x64) to install a kernel mode driver then though installation is successful and driver is in running state but still it logs an error event in event viewer with following details.

On debug I've found that as soon as below API gets called we see error entry in event viewer. Even though API returns success.

if(!UpdateDriverForPlugAndPlayDevicesW(NULL, hwid.c_str(), infpath, flags, &reboot)) {

{

}

I have checked devcon install with windows sample driver as well, and seeing same problem.

Note: Issue is not observed in windows 10 OS. it only appears for windows11

Is this a known issue, how can we fix it with devcon.exe install?
