The reason I ask is you could be asking a different question. But let's say you want to stop the print spooler from starting on boot. Did you not only stop the service but disable it?
http://www.tenforums.com/drivers-hardware/15838-print-spooler.html contains the usual commands for starting and stopping and there's plenty more on the web about services and settings.
When I turn off windows print managing in the settings area it comes back on when I reboot... How do I keep it off after a reboot
