You can do this sort of thing in perl using the Win32::Service module. I've never used this module but its fairly simple and probably a good start if you've never used perl.

You can also simply start and stop services on the command line in Windows using "net start" and "net stop" commands. These you can add into a batch file and run from that. Eg to start the printer spooler you type "net start spooler". You only limited access though as to which services you can stop and start this way.
