博客介绍了服务配置程序删除服务的操作。通过OpenService函数获取对已安装服务对象具有DELETE访问权限的句柄，再利用DeleteService函数结合该句柄，将服务从SCM数据库中移除。

Deleting a Service

In the following example, a service configuration program uses the OpenService function to get a handle with DELETE access to an installed service object. The program then uses the service object handle in the DeleteService function to remove the service from the SCM database.

BOOL DeleteSampleService() 
{ 
    schService = OpenService( 
        schSCManager,       // SCManager database 
        TEXT("Sample_Srv"), // name of service 
        DELETE);            // only need DELETE access 
 
    if (schService == NULL)
    { 
        printf("OpenService failed (%d)/n", GetLastError()); 
        return FALSE;
    }
 
    if (! DeleteService(schService) ) 
    {
        printf("DeleteService failed (%d)/n", GetLastError()); 
        return FALSE;
    }
    else 
        printf("DeleteService succeeded/n"); 
 
    CloseServiceHandle(schService); 
    return TRUE;
}
