pnputil -d是指 -e枚举出来对应的oem*.inf文件 

记录给自己看的；

#include #include 
#include 
#include bool is64BitOs()
{auto hModule = GetModuleHandle(L"kernel32.dll");if(hModule && GetProcAddress(hModule, "IsWow64Process")){return true;}return false;
}const QString infFile = "test.inf";int main(int argc, char *argv[])
{QCoreApplication a(argc, argv);QProcess p;QString program;if(is64BitOs()){program = QString("C:\\Windows\\sysnative\\pnputil");}else{program = QString("C\\Windows\\System32\\pnputil");}p.start(program, QStringList() << "-e");p.waitForFinished();auto info = QString::fromLocal8Bit(p.readAllStandardOutput());if(info.contains(QStringLiteral("Silicon Labs Software"))){std::cout << "already installed Silicon Labs Software" << std::endl;}else{std::cout << "not installed" << std::endl;std::cout << "install start: " << std::endl;p.start(program, QStringList() << "-i" << "-a" << infFile);p.waitForFinished();std::cout << p.readAllStandardOutput().date() << std::endl;std::cout << "install finshed: " << std::endl;}
