Here’s a snippet of code I wrote that will force a Windows batch script to run in a minimized window. Insert it at the beginning of the script:

if not "%minimized%"=="" goto :minimized
set minimized=true
start /min cmd /C "%~dpnx0"
goto :EOF
:minimized
rem Anything after here will run in a minimized window

It works by having the script re-launch itself in a new minimized window. There are a few juicy batch scripting tricks in here that I recently picked up, like the %~dpnx0 syntax and the special :EOF label. And the overall flag/callback syntax is generally useful for creating self-contained batch scripts.

Other start switches besides /min can provide different parameters for the child window, such as adjusting the CPU priority of the resulting process.
