I would like to make a script that will run a batch file on my desktop. How do i do that?

Create a script in Pulseway that runs the batch file, like this:

"c:\users\jayden\desktop\batch_file.bat"

You may want to read up on how to actually create scripts in Pulseway by reading the manual:
https://intercom.help/pulseway/en/articles/821208-configuring-automation-tasks

 

your missing the point of pulseway, why would you want to ever run a batch file located on your desktop, copy the batch file to pulseway and run it from there.
