我正在开发Windows 8.1信息亭类型的应用程序，我需要将组策略自定义用户界面设置设置为应用程序的.exe。当然，这可以手工完成，但我希望能够通过c＃或安装程序（我现在正在使用Visual Studio安装程序）进行更改。
感谢您的帮助！

要走的路是：
现在，直到实施： - ）
请检查以下代码。这是我最终通过分析和借用来自不同资源的不同代码片段实现的实现：
public class LSAManager
{
[DllImport("advapi32.dll", PreserveSig = true)]
private static extern uint LsaOpenPolicy(ref LSA_UNICODE_STRING SystemName, ref LSA_OBJECT_ATTRIBUTES ObjectAttributes, Int32 DesiredAccess, out IntPtr PolicyHandle);

winErrorCode = LsaNtStatusToWinError((int)res);
LsaClose(policyHandle);
}
FreeSid(sid);
}
return winErrorCode;
}
}
为方便起见，我已将此代码放在一个名为 LSAManager 的单独类中。要使用此代码，只需调用：
string userName = "alex";
// Set "Logon As a Service" privilege (for example):
if (LSAManager.SetRight(userName, "SeServiceLogonRight") != 0)
{
// handle error here
}
