How can I hide ms-dos window when running a .bat file?

Use a VBScript

Set objShell = WScript.CreateObject("WScript.Shell")objShell.Run("C:\yourbatch.bat"), 0, True

Run that which will run your batch file hidden.

I don't like VBScript solution.

Download and copy nircmd.exe to your %systemroot%\system32 folder, then add this command to first line of your batch:

nircmd.exe win hide ititle "cmd.exe"

or make your batch title custom first with title command to avoid from hiding all cmd windows, like this:

title MyBatchnircmd.exe win hide ititle "MyBatch"

This VBScript creates a copy of your batch file in %Temp%, executes it silently and deletes it afterwards
