搜了一下，看起来非常简单
To create a Windows Service from an executable, you can use sc.exe:
sc.exe create <new_service_name> binPath= "<path_to_the_service_executable>"但是：
Note that it will not work for just any executable: the executable must be a Windows Service (i.e. implement ServiceMain). When registering a non-service executable as a service, you’ll get the following error upon trying to start the service:
Error 1053: The service did not respond to the start or control request in a timely fashion.
那就只能用第三方的了，有人推荐用NSSM：
NSSM – the Non-Sucking Service Manager
名字简单又暴力，使用也是很简单暴力
下载，解压，找到32或者64位的exe
开一个管理权限的cmd，nssm.exe install SERVICENAME
回车，就有gui了，跟着gui走，完工
