这个网站,使用注册表而不是WMI(未经测试):

public static DateTime GetWindowsInstallationDateTime(string computerName)
{
    Microsoft.Win32.RegistryKey key = Microsoft.Win32.RegistryKey.OpenRemoteBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, computerName);
    key = key.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion", false);
    if (key != null)
    {
        DateTime startDate = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
        Int64 regVal = Convert.ToInt64(key.GetValue("InstallDate").ToString());

        DateTime installDate = startDate.AddSeconds(regVal);

        return installDate;
    }

    return DateTime.MinValue;
}
