Don't want shutdown script to run on restart

Hi,

I've got my system configured via gpedit so that it runs a custom batch script when it shuts down. The script can take about a minute to complete because it is telling some external hardware to run through its power down procedure. However when I tell the system to _reboot_ the script still runs and then when the system starts back up it has to run the startup script to power the hardware back up again.

Therefore I wondered if there is a way to tell Windows not to run the script if the action is reboot, not shutdown, or can I get access to the action via some parameters that can be passed to my script?

Searched through forums but can't find any answer to this - maybe the search terms are too common.

Many thanks

That's fine, but how can I tell if the current operation is shutdown or restart? Is there a parameter list I can pick up and pass on to the script as command line args?
