For some reason, I just needed to do something like this, so here is a quick how-to:
There is a tool named sc.exe in the Win 2K Resource Kit, however I believe it also exists in Windows XP, as I did not have to do anything, and was able to access it from command-line.
Using this tool, you can see the list of the services that are currently running, add, delete, create or stop services.
The syntax for creating a service is like this:
sc create [service name] [binPath= ]
What this command does is basically the same as the CreateService API function.
Similarly, the commands to achieve other purposes are:
sc delete
sc start
sc stop
For more information you can have a look at here.
You can also view services existing on the system or even delete them from this registry key :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
Oh, and by the way, if; for some reason you need to get ahold of Windows 2000 Resource Kit Tools, you can get them here.
