如果你非法卸载一个软件后，该程序可能有残留的win32服务在系统里，而windows在mmc里并没有提供卸载服务的功能。在.net里可以通过Installutil.exe 来安装/卸载服务，其实对于非.net的windows服务，微软提供了一个工具来管理服务，可以删除服务，在WinXP的system32目录下有个叫sc.exe的工具，该工具包含在Windows 2000的Resource Kit中，这个工具有很强的管理服务的功能!
在cmd里运行sc.exe可以看到如下内容：
C:\WINDOWS\system32>sc.exe

QUERY and QUERYEX OPTIONS :
If the query command is followed by a service name, the status
for that service is returned. Further options do not apply in
this case. If the query command is followed by nothing or one of
the options listed below, the services are enumerated.
type= Type of services to enumerate (driver, service, all)
(default = service)
state= State of services to enumerate (inactive, all)
(default = active)
bufsize= The size (in bytes) of the enumeration buffer
(default = 4096)
ri= The resume index number at which to begin the enumeration
(default = 0)
group= Service group to enumerate
(default = all groups)
SYNTAX EXAMPLES
sc query - Enumerates status for active services & drivers
sc query messenger - Displays status for the messenger service
sc queryex messenger - Displays extended status for the messenger service
sc query type= driver - Enumerates only active drivers
sc query type= service - Enumerates only Win32 services
sc query state= all - Enumerates all services & drivers
sc query bufsize= 50 - Enumerates with a 50 byte buffer.
sc query ri= 14 - Enumerates with resume index = 14
sc queryex group= "" - Enumerates active services not in a group
sc query type= service type= interact - Enumerates all interactive services

如果你要卸载一个本地服务，可以：

当然你也可以用这个工具create,start,stop服务。
