Just want to add that key is found,
qDebug() << "child keys = " << reg.childKeys();
result in
child keys = ("Common Administrative Tools", "Common AppData", "Common
Desktop", "Common Documents", "Common Programs", "Common Start Menu",
"Common Startup", "Common Templates", "CommonMusic", "CommonPictures",
"CommonVideo", "OEM Links", "Personal")
but value returned is empty string - different from visible in regedit
