{
    WindowsIdentity identity = WindowsIdentity.GetCurrent();
    string path = string.Format("{0}\\Software\\Microsoft\\MediaPlayer\\Preferences", identity.User.Value);
    RegistryKey key = Registry.Users.OpenSubKey(path, true);
    if (key == null)
        throw new Exception("Error! Registry not found!");
    key.SetValue("CurrentEffectPreset", value, RegistryValueKind.DWord);
