在Windows服务的安装类ProjectInstaller中加入以下方法：

protected override void OnCommitted(System.Collections.IDictionary savedState)
        {
            base.OnCommitted(savedState);
            //将服务更改为允许桌面交互模式
            ConnectionOptions coOptions = new ConnectionOptions();
            coOptions.Impersonation = ImpersonationLevel.Impersonate;
            ManagementScope mgmtScope = new System.Management.ManagementScope(@"root\CIMV2", coOptions);
            mgmtScope.Connect();
            ManagementObject wmiService;
            wmiService = new ManagementObject("Win32_Service.Name='这里是当前服务名'");
            ManagementBaseObject InParam = wmiService.GetMethodParameters("Change");
            InParam["DesktopInteract"] = true;
            ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", InParam, null);
        }
