How to unlock a computer i brought an use hp computer, And it has a personal password lock. how can i unlock it?

In an earlier post I had written about how to create an invisible folder. That’s a method to create a merely invisible folder with no real protection.
Now, here we will see how to create a folder that will not just be invisible, but also require a password to reveal it and open it. The best part is that you don’t need any special software to do this. Just plain old Notepad is all that you need.
Here is the code that you need:
cls
@ECHO OFF
title Folder Personal
if EXIST “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” goto UNLOCK
if NOT EXIST Personal goto MDLOCKER
:CONFIRM
echo Are you sure u want to Lock the folder(Y/N)
set/p “cho=>”
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Personal “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
attrib +h +s “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock folder
set/p “pass=>”
if NOT %pass%==pwd123 HERE goto FAIL
attrib -h -s “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
ren “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” Personal
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Personal
echo Personal created successfully
goto End
:End
Now here is what you need to do:
Just copy the above code and paste it into Notepad. Save it by giving it any name you choose. Assuming, the file is called secret.txt, change the extension to ‘.bat‘ so that the new name becomes secret.bat. What you get is a batch file. You could actually save one step by saving the file in Notepad directly as secret.bat by enclosing the file name like this: “secret.bat” . This batch file is the one that you need. You can edit this batch file to change the folder name and the password. To change the name of the folder that is created, change the ‘Personal’ (in bold in the above code) to any another name you choose. Likewise change the ‘pwd123′ (in red in the code) to anything else.
Now let’s see how to use it. Place the file in the location where you would like to create your protected folder. Run the batch file by double clicking on it. This will create a folder named Personal in the same location as the batch file. You can now open this folder and place any files in it. Once you are finished, run the batch file again. You will be asked whether you want to lock the folder. Entry ‘Y’ (for Yes) and hit Enter. The folder becomes invisible. To retrieve the folder, run the batch file again. You will be prompted to enter the password. Enter the password, hit enter and voila! the folder appears.
Important: The batch file acts like a key to open the locked folder. So once you have created and locked a folder, do not keep the batch file in the same location since anybody can open the batch file and view your password. So I would suggest that you keep the batch file in a separate and safe place or better still keep it on your pen drive or flash drive. That way when you want to open the folder just copy the batch file to the location where you have your protected folder and run it.
Do remember that the above method is not intended to act as a substitute for the numerous free and commercial softwares that are specifically designed to provide security and encryption to your data.
Update: I got comments saying the code does not work. Of course I did check it before posting it here. But I have identified the problem. The problem is with the straight double quotes used in the code in this post. Once you copy the code you would also need to change each of the double quotes with your keyboard double quotes. That might seem a lot of work for some. So I thought it would be easier to give away the batch file itself. You can download the file here. (Use right-click and ‘Save Target as’ or ‘Save Link as’).
