微软的介绍：
Creates a service entry in the registry and Service Database.
SYNTAX:
sc create [service name] [binPath= ] <option1> <option2>...
CREATE OPTIONS:
NOTE: The option name includes the equal sign.
type= <own|share|interact|kernel|filesys|rec>
(default = own)
start= <boot|system|auto|demand|disabled>
(default = demand)
error= <normal|severe|critical|ignore>
(default = normal)
binPath= <BinaryPathName>
group= <LoadOrderGroup>
tag= <yes|no>
depend= <Dependencies(separated by / (forward slash))>
obj= <AccountName|ObjectName>
(default = LocalSystem)
DisplayName= <display name>
password= <password>
提示大家：sc cretate命令后面带的参数比如[binPath= ]的等号后面必须有个空格，没空格你怎么折腾都不行的，哈哈。微软还真搞笑啊，搞这么个功能迷惑人。同样，后面的其它参数比如group= , displayname=的等号后面都需要空格，不然sc create命令不会成功创建服务，只会返回给你帮助信息。
sc create nlsvc binpath= "F:\Program Files\NetLimiter 2 Lite\NLClient.exe" type= own start= demand DisplayName= NetLimiter
这个是成功的
