[Interest] Fail to fetch Windows MachineGuid using QSettings

[Nuno Santos]

Hi,

I'm trying to fetch MachineGuid from Windows registry using QSettings 
but the output is always an empty string.

QSettings 
settings("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Cryptography", 
QSettings::NativeFormat);
qDebug() << settings.value("MachineGuid").toString();

Is there any kind of access control that might be blocking this?

Should I use native Windows calls for this?

Thanks,

Nuno
