How to Run a Batch File Only on Shutdown (Not Restart)?

[BennyLe]

Hey everyone,

 

As the title suggests, I’m trying to create a task that runs a batch file specifically when I shut down my PC, but not when I restart it.

ChatGPT has been helpful, but I’m still unsure how to set this up. Is this possible to achieve? If so, how would I go about it?

 

Thanks in advance for your help!

If you manually run the batch file, at the end of your batch file use the shutdown command.

e.g. shutdown /s /t 0

should try to shut down your PC immediately.

Would be helpful for us, if you could share what you've already tried/what answer you got.

 

The problem with running a script at shut down is that the system is shutting down. So you have a very limited time to do anything before your script gets terminated. You could potentially have a script that cancels shutdown, does whatever it needs to do, then schedules the shutdown again.

Uhh its easy make script that needs to do something then at the end script just shutdown command. Only difference you have different shutdown shortcut.

Yes, I know. But it's not necessarily "convenient" (or easy to forget) to shut down using the script, rather than normally

As far as I can tell you can't intercept a shutdown signal. 
Best way to do this would be to remove the shutdown option from the power options in the Start Menu and add a line to the end of your script that does the shutdown action ( shutdown /sg /t 0 /f )

I have an idea, instead of plugging the shutdown button to the motherboard, use some kind of intermediary hardware and disguise this as a hid input device that either acts as a specifc button not on your keyboard (like the lenovo vantage button that calls their app), or activates a extremely complex hotkey sequence that you won't use irl. And have a service that executes your batch file upon recieving command.
