Hide Command Window of .BAT file that Executes Another .EXE File

Using start works fine, unless you are using a scripting language. Fortunately, there's a way out for Python - just use pythonw.exe instead of python.exe:

:: Title not needed:
start pythonw.exe application.py

In case you need quotes, do this:

:: Title needed
start "Great Python App" pythonw.exe "C:\Program Files\Vendor\App\application.py"

Using start works for me:

@echo off
copy "C:\Remoting.config-Training" "C:\Remoting.config"
start C:\ThirdParty.exe

EDIT: Ok, looking more closely, start seems to interpret the first parameter as the new window title if quoted. So, if you need to quote the path to your ThirdParty.exe you must supply a title string as well.

Examples:

:: Title not needed:
start C:\ThirdParty.exe

:: Title needed
start "Third Party App" "C:\Program Files\Vendor\ThirdParty.exe"

Create a .vbs file with this code:

CreateObject("Wscript.Shell").Run "your_batch.bat",0,True

This .vbs will run your_batch.bat hidden.

Works fine for me.
