Windows 7 C# 上已安装的更新列表

Question

通过 Microsoft Ultimate Wisdom，他们更改了注册表中的更新位置。我可以毫无问题地从 Windows 2003 Server 获取更新。只是 Windows 7 已不再流行：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

任何人都可以通过其他方式获得它。最好用 C# 或使用 WMI？

上帝用他们的智慧拯救微软

对于 Window 7 64 位，它位于 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Updates 中

Answer 2

private string GetX64Installedsoftware()
{
    string Software = null;
    string SoftwareKey = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";

    Software += "\r\nWINDOWS X64 Software\r\n\r\n\r\n ";
    using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(SoftwareKey))
    {
        if (rk == null)
        {
            return Software;
        }
        foreach (string skName in rk.GetSubKeyNames())
        {
            using (RegistryKey sk = rk.OpenSubKey(skName))
            {
                try
                {
                    if (!(sk.GetValue("DisplayName") == null))
                    {
                        if (sk.GetValue("InstallLocation") == null)
                            Software += sk.GetValue("DisplayName") + " - Install path not known \r\n ";
                        else
                            Software += sk.GetValue("DisplayName") + " - " + sk.GetValue("InstallLocation") + "\r\n ";
                    }
                }
                catch (Exception ex)
                {
                }
            }
        }
    }
    return Software;
}
