Instructables
Do you have a computer that someone knows the password, or are to lazy to lock the computer when you leave, even for a minute? Well this is an instructable our friendly neighborhood nerd has made for us. You will need:

a computer (running Windows 3.1 or higher)
notepad or other simple text editing software
arms and legs are optional if you have speech recognition
keyboard

NOTE:This will not work on Macs (sorry macs)

Step 1: Open Notepad

First open notepad.

Win 95-2000, Me
Start>Programs>Accesories>Notepad

Win XP and up
Start>All Programs>Accesories>Notepad

If you see the window shown below then you have notepad.

Step 2: Code

Picture of Code
Copy and paste this code:

dim Password
dim Input

Password = inputbox ("Enter the password","Password","Enter text here")
do
Input=inputbox ("This computer is locked. Enter the password.","Password","Enter text here")
if Password = Input then
a=msgbox ("Correct! Welcome back.",0+64,"Computer")
else
if Input = "0000" then
b=msgbox ("Reset code entered.",0+64,"Computer")
else
c=msgbox ("Incorrect. Try again.",0+16,"Computer")
end if
end if
loop until Password = Input or Input = 0000

Step 3: Reset Code

Look for the part of the code that says

if Input = "0000" then

and also

loop until Password = Input or Input = 0000

These are the program's reset codes. If you forget your password the reset codes will allow you in. You can change them to any number you want but both the 0000 parts of the code must be the same for this to work. For example they could be the year you were born or your house #.

Step 4: Save Me!!

To make this script work we need to save it in a special way, follow along carefully. :o

Go to
File>Save As

Now we can save it as anything you want, but it has to end with the file extension .vbs

ex.
CompLock.vbs

Step 5:

Picture of
Test this program. The best part of this program is you can add a new password every time, so if an annoying sister, brother, parent, co-worker ect. finds out your password you can add a new one the next time you run this program. As always comment any problems this program has so I can debug it. Super_Nerd signing out.

im using this code can anyone help me with the line in the { }'s
@echo off
Title computer lock
cls

:Lock
echo "Please inter a password to lock your computer"
set/p "1Pass=>"
taskkill /IM explorer.exe
cls
echo "This Computer is locked."

:Locked
taskkill /IM explorer.exe
echo "Please type the password to unlock the computer"
set/p "2Pass=>" {this line needs to be skiped if nothing is enterd so it becomes a if enter key hit then take entered value and set it as varlable 2pass anyone know a way to do that?}

:Unlock
if %1pass%==%2pass% then goto End
goto Locked

:End
echo "Have a nice day!"
PAUSE
I know this is sort of too late, but I couldn't help myself. Here is the edited code:

@echo off
Title computer lock
cls

:Lock
echo Please inter a password to lock your computer
set /p 1Pass=>
taskkill /IM explorer.exe
cls
echo This Computer is locked.

:Locked
taskkill /IM explorer.exe
echo.
echo.
echo Please type the password to unlock the computer
set /p 2Pass=>

:Unlock
if %1pass%==%2pass% then goto End
goto Locked

:End
echo Have a nice day!
PAUSE

I don't exactly get what you mean, but from what I can tell, it seems irrelevant. The code is already doing what you asked.

Tip: Don't spam quotation marks.

Excellent job, as per usual. But, can't they just exit out of it? It isn't very effective. Can you make it more so?

When i run it says it's lock but i still can open folders and applications it dosent seam to lock can you help?
Super_Nerd (author)  BigMikeDog2 years ago
You could make it stop explorer.exe and restart it when the password is entered. I'm not very good with windows shell objects but you can make it run a batch file to stop and restart explorer.
ok thanks i know that will work but i got know idea how do do that :- \
Super_Nerd (author)  BigMikeDog2 years ago
Sorry but I'm not the best at batch files. Maybe you could try

taskkill explorer.exe

to freeze any background use

and in another file

start explorer.exe

to unlock the computer
Sorry if this doesn't work.

yep they both work but you do taskkill /IM explorer.exe
the only problem is that 7 is protected form killin the program so then i just restarts it self
lol for mine if you click the x button two times it sais correct welcome back
Super_Nerd (author)  knexinglemon3 years ago
That' because when you press the x, without entering anything, the computer assumes your password is nothing. When you x again, nothing was entered just like when you x-ed before, so it lets you back in.

What stops the user from simply minimising the popup?
Super_Nerd (author)  lanky.ninja3 years ago
There isn't a minimize button, and the X is greyed out. The only way to stop this from running is to go to task manager and kill the wscript.exe process. This isn't brick solid though, as you can still use the computer behind this. This program was intended to keep people who don't know much about computers off. A way to make this more secure would be to disable explorer.exe until the computer is unlocked.
I guess it would for complete ludites
