Windows Service is an executable program that is installed in a registry database maintained by the Service Control Manager. The service can be started at boot time by a boot program or by the system, or it can be started on demand by the Service Control Manager.
However, most application programs are not a service and it is hard to change the normal application program to the service. GeneRally, it needs an additional development by the software vendor.
Microsoft's SrvAny.exe included in the NT resource kit handles user-defined service but it is hard to understand and needs registry manipulations. Srvany can't process the application program's shut down behavior, so it can't be executed as a service properly.
ServiceShell simplified the work !
With ServiceShell, you can register your normal application program as a service and manage it easily. Once your application program changed to the service by ServiceShell, it will be started at boot time (before log-in) and stay running even if the Windows session being ended.
ServiceShell controls each registered services systematically, prepared for system errors, shut down problems of user-defined services.
