How To Keep A System Open For Long Duration Using Batch Script

Introduction
This article is very useful in order to keep your system open/unlocked for long duration.
Sometime in some of projects/process(more specific at the time of any Training or meeting) it is required to keep the system open for long duration, for those scenarios if an user want to take a break then it’s not possible for him/her to leave their system because the process is still running , and it might will get stopped or end if the system gets locked.
And to avoid this kind of scenarios we need a program that will keep our system busy for long time or interrupt it before every three minutes.

Description
This batch file will keep your system open for a long duration. And a user can go for a break whenever he/she wants.
More specific, this script will press “Num Lock” in every 2 minutes and will keep your system busy. Just follow below mentioned steps.

Procedure
We need to do only two minor jobs in order to achieve this goal.
1. Create a .vbs file (eg: keyboard.vbs) in C drive
2. Create a batch file to call .vbs file

Steps
1) Open a notepad (Run---->notepad or click right button of your mouse---->new---->text document)

2) Copy the below mentioned script in notepad

Code:

Set WSHShell = WScript.CreatObject("WScript.Shell")
WSHShell.sendkeys"{NUMLOCK}"
WSHShell.sendkeys"{NUMLOCK}"

3) Save this file with .vbs extn (eg: keypress.vbs) in C drive.
4) Open another notepad and paste the following scripts in it.

Code:

@echo off
rem ===== this scrip will not let your system locked for a period defined by you =====


echo Set WSHShell = WScript.CreatObject("WScript.Shell") >>C:\keypress.vbs
echo WSHShell.sendkeys"{NUMLOCK}" >>C:\keypress.vbs
echo WSHShell.sendkeys"{NUMLOCK}" >>C:\keypress.vbs

echo.
echo Enter following details

rem  -- Set WSHShell = WScript.CreatObject("WScript.Shell") >>C:\keypress.vbs
rem -- WSHShell.sendkeys"{NUMLOCK}" >>C:\keypress.vbs
rem -- WSHShell.sendkeys"{NUMLOCK}" >>C:\keypress.vbs
