在Windows7 C#上安装的更新列表

Question

使用Microsoft Ultimate Wisdom，他们已经更改了注册表中的更新位置。我可以从Windows2003服务器上获取更新，没有问题。只是Windows 7已经不再流行了：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

任何人都有其他方法得到它。最好是用C#或使用WMI？

上帝用他们的智慧拯救微软

Answer 1

对于Windows7 64位，它是HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Updates格式

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;
}
