If you are logged on any PC and want to change it password without any software and knowing the old password can you do it.. Ya Of course by this method you can change the password when you gain the access on PC.
First step is to set a backdoor in windows, backdoor simply means gaining access which can be also use in future So let start the real fun
Open The command prompt (run as administrator in win7&vista)
Now after it is open type the following given command
Syntax : net user account.name *
( specify the user account name like admin in place of account.name)
Then press enter and give any password for that account
Did you see friends your new password had been set and no old password was required to conform it
Just imagine that in anyway you got access to command without log on then you can change the password
Now Next Step is to press the shift key five times then you will get a dialog box called sticky key on your screen
By this sticky keys multiple keys can be press at a time,
this feature can be used at logon screen by pressing shift key five times.
Whenevr we start an application like paint or other, we were actually running mspaint.exe placed in the C:\windows\system32. or command prompt, we are running cmd.exe placed in system32 directory, similary
When shift key is press 5 times , system actually starts the executable file
sethc.exe placed in system32 directory. This means if we rename cmd.exe to sethc.exe and press shift 5 times, system would again start sethc.exe but instead of sticky keys the command prompt will be opened.
You can simply change it or renamed it see below for that:-
Go to C:\windows\system32
* Copy cmd.exe onto the desktop and rename to sethc.exe .*Now again copy that file and paste it to system32 directory.
@ Windows XP Users
Hopefully existing orignal sethc.exe must have been replaced and you had done. then press shift five times and you see command prompt on screen.You can access it at windows logon screen and change or clear the pass easily using "net user" command.
Note: You can also do these changes while using Guest Account. But when you will access command prompt , you can change or clear the password of administrator's account also . This is the fun hack by which we can hack into administrator's account by guest account.
@ Windows vista/7 Users
You had got a pop up box showing "Access Denied".
really we can not change system32 directory files until unless we don't have the permissions . You can not have the permissions until you do not have the ownership. So lets take ownership, change permissions, just follow the steps.
1. Right click on sethc.exe and run as administrator. Again right click on sethc.exe, open properties.
Click on Advanced tab , then on owner and click edit, change the owner from "trusted installer" to "administrator" and click apply.
2. Now click on 'Edit' in the security tab to edit the permissions. Click on 'Administrators' , give it full control
and apply changes.
Now it is done
Now try to replacing the orignal sethc.exe with our sethc.exe (that we got by renaming cmd.exe).
Press shift key five times and hopefully you would get command prompt on the screen instead of sticky keys.
Now Enjoy Command prompt at logon screen...
So if you get your friends laptop for a while then do not forget to set up a backdoor
