Hide window when running PowerShell scripts in Task Scheduler

Whenever you run a PowerShell script, a PowerShell window opens. You don't want windows to appear in cases where you want the script to run in Task Scheduler.
I will explain how to execute the PowerShell script with the window hidden.

JScript

You can hide the window by calling a PowerShell script from WSH(Windows Script Host).

filename: launch_ps.js

var shell = WScript.CreateObject("WScript.Shell");
var args = WScript.Arguments;

var cmd = ""
for(var i=0; i < args.length; i++) {
  cmd += " " + args(i)
}
var ret = shell.Run("powershell.exe -ExecutionPolicy RemoteSigned -File" + cmd, 0, true);
WScript.Quit(ret);

Registration in task scheduler

This section describes registration to the task scheduler under the following conditions.

launch_ps.js : Script above
test.ps1 : PowerShell script you want to launch

Place these two in c:\temp

Item	Set value
Program/script	wscript
Add arguments	launch_ps.js test.ps1
Start in	c:\temp

Please replace according to each environment.

What can't be achieved without JScript is a bug called the PowerShell specification.
