The Windows NT Resource Kit provides two utilities that allow you to create a Windows NT user-defined service for Windows NT applications and some 16-bit applications, but not for batch files.
Instrsrv.exe installs and removes system services from Windows NT and Srvany.exe allows any Windows NT application to run as a service.
Steps to create a user-defined service
To create a Windows NT user-defined service, follow these steps:
At an MS-DOS command prompt(running CMD.EXE), type the following command:
path \INSTSRV.EXE My Service path \SRVANY.EXE
where path is the drive and directory of the Windows NT Resource Kit (for example,
C:\RESKIT) and My Service is the name of the service you're creating.
C:\Program Files\Resource Kit\Instsrv.exe Notepad C:\Program Files\Resource Kit\Srvany.exe
To verify that the service was created correctly, check the registry to verify that the ImagePath value under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\service nameis set to point to SRVANY.EXE. If this is not set correctly, the service will stop shortly after it starts and return an Event ID 7000 (The service name failed to start).
Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

- Data Type: REG_SZ

where <path>\<application.ext> is the drive and full path to the application executable including the extension (for example, C:\WinNT\Notepad.exe)
Close Registry Editor.
By default, a newly created service is configured to run automatically when the system is restarted. To change this setting to Manual, run the Services applet from Control Panel. Then change the Startup value to Manual. A service set to Manual can be started in one of several ways:
From the Services applet in Control Panel
From an MS-DOS command prompt, type the following command:
NET START <My Service>
Use the Sc.exe utility from the Resource Kit. Type the following command from an MS-DOS command prompt:
<path>\Sc.exe start <My Service>
where <path> is the drive and directory of the Windows NT Resource Kit (for example,
