Be nice kids.

First of all, and I have to say this because of some recent comments, this is not a virus, and will not delete any files from your computer. In fact, ophCrack, the software we're gonna use is a very popular password cracker. Google it or Wikipedia it if you don't believe me.

This works for WINDOWS ONLY
UPDATE: WORKS FOR XP AND VISTA

This will crack all windows passwords up to 14 digits on a computer.
You need physical access to the computer.
You don't need to be logged in (that's what this is for).
It will tell you all user names and passwords on the computer.

Step 1: Get the resource

1. Go here:
http://ophcrack.sourceforge.net/download.phphttp://ophcrack.sourceforge.net/download.php

2. Download the latest version of ophcrack live cd. To crack passwords on an XP computer select 'ophcrack XP LiveCD'. To crack passwords on a VISTA computer select 'ophcrack VISTA LiveCD'.

3.The software you download will be a CD image (.iso format). If you try opening this on a computer with a CD-Writer and CD-Writing Software (eg. Nero, Roxio, Record Now, or whatever you have) it will write that file to a CD.
So, make the CD

Aftear launching the cd it comes to a screen that says "Welcome to open source SliTaz boot time: 12 s. Run: 'ophcrack -launcher.sh dialog' to search again for tables. tux@slitaz:~$" I'm assuming it is waiting for a command. I have a vista hplaptop and made sure I downloaded the live cd for vista. Can anyone help

When I lost my Windows password, I try to find out one program from Google, finally use a tool to crack the Windows 7 login password, and it seems to supports all the Windows OS. I got this smart Windows key from CNET website: Windows password recovery

Actually to crack or hack Windows password, I use the SmartKey Windows Password Recovery, it is nice and wonderful! It works like a charm! You can Google it!

kernel panic – not syncing: Attemped to kill the idle task – this is what I got on the screen after selecting a mode with Ophcrack.. and downloaded the file twice and burned it twice.. got the same message..Eventually I purchase the paid software Password Recovery Bundle and it works! Thanks any way!

ok so i put the boot up menu in the right order, i went into the bios set up and changed the boot sequence to "CD/DVD/CD-RW Drive" then "Internal HDD" and i hit esc and then it went through the black linux screen and scrolled down and then went to this white screen that says "ophcrack Live CD" with 4 characters to the side and options to the right. asking for "ophcrack Graphic mode - automati, manual. low ram, and text mode." it started automatically in auto mode and then went to this black screen again and loaded a bunch of dots.

after that it went to this next screen that was all brown and had a large OS in the corner and ophcrack LiveCD along the top and this black box menu that stated. "tables found (mntsr0tablesvista_free), and "list of windows partitions containing hashes (0. mnt/s da2/windows/system32/config)(1. /mnt/s da3/windows/system32/config)", and then "select the partition to crack::" ...what did i do wrong or what am i suppose to do...i have a dell studio with windows vista please help.

I have tried about 7 of these instructables to go around or reset admin. password and NONE OF THEM work.
ive tried at least 15 of them already and its just like you.  NONE OF THEM WORK!!!!
try this program called password-nuker, it resets your SAM file on boot
try my instructable. you don't need any software, just an account on the computer or the computer's network. http://www.instructables.com/id/how-to-change-windows-passwords-without-logging-on/
i read your instructable first of all the account needs to be an administrator also it dose not work for vista i dont really like it (no offence to you what so ever)
boom-man, the account does NOT need to be an administrator (at least not on the computers i've tried, i have no clue where you've tried) i never said it would work for vista, it says WINDOWS XP in there, just read it carefully. i really don't care that much whether you like it or not, any feedback is good feedback.
try harder, but you're right, most of them only work when you're already admin... This will work (if bootCD isn't locked down in bios) mine will work too I haven't seen other methods on here

hello! nice to have this tool,  do you know if it works on windows 7?

AVG says this is an unwanted risky file. It did not load to CD but installed on download computer. This is a bad file to try to use.
A.C.E. shortman5 years ago
and you must have downloaded the executable file. if you want to burn it to a disc you need the iso.
Hello again A.C.E. lol.
 Hello again spartan 2209....

  I'm sorry, i actually have no idea who you are..

                     Everyone was doing it.
Haha funny thing is I've seen you on other instructables many times :P
 Yeah i get that =D

I like this community
of coarse it says its risky! its a password cracker stupid

Technically, every anti-virus scanner I use say something like this, " Warning! Virus PSW.PSWdump has been found" or something like that.

It goes like this, PSW.PSWDump.at (Unclassified Threat)

How do you get the windows vista startup to look like that?
Wow, are you forgetting the TINY detail that you have to be an administrator to download and install. Good try though.

I had my doubts as to if this would actually work, but my first comment turned around and bit me in the arse and i was totally amazed that it worked, but seriously it went to my head a little bit and i kinda went crazy(me and friend) at school with this. Found Head Admins PW All head teachers PW everyones, pretty cool if you ask me.

RAINBOW FILES PEOPLE!!!!! RAINBOW FILES!!!!
look em up, make em, USE EM!!! u can crack a 14 number and letter password in aprox 2mins max

He he he he, i got 125gig of tables, i can crack nt lm passwords number/letter/symbol at a 96% hit rate :) **evil laugh** ok very serious

here are some helpful things to follow
LOOK UP
LEARN
LOOK UP SUM MORE JUST TO BE SURE
LEARN WHAT YOU NEED TO
AND USE UR KNOWLEDGE IT CAN GET YOU PLACES!!!! money tooo
If I have used pwdump to get a list of usernames and passwords, how do I crack the hashes
1st step learn about rainbow files, learn what your variables could be, or your possible variables could be
2nd make rainbow files
3rd download cain&able or another program thats similar. and be on your way
4th step if your lazy and don't care about time, use a bruteforcer

IM SERIOUSLY NOT GOING TO EXPLAIN TO YOU HOW IT WORKS!!!! WASTING MY TIME!!! ITS SIMPLE! USE WIKIPEDIA OR WHAT EVER!!!!!!!!!!!!!!!!! etc
"2nd make rainbow files" Have you ever created rainbow tables? Do you know how cpu intensive and time consuming this is? Especially if you need a full character set table generated. Not to mention if you need more than 8 characters. You'll need a 100 GPUs running about 2 years to generate a highly successful and relaible rainbow table.
uselesss, my computer file is 100 letters randomly typed and now remembered by me i remember the whole thing!!!!YOu cann't crack that in less than 10 hours i bet
i know how to generate new sam files. if cracking doesn't work. ill just replace the sam file leaving no passwords
i did a 512 - bit encryption and i made it so it is impossible to delete unless you fry the cpu or something
haha nah it dusnt work that way, the sam file contains info about the pc including specs, keys, passwords etc etc. as long as i got the cd key i can replace the sam file. jsut gota detect specs, enter product key and its ready to go lm and ntlm encryptions don't phase me anymore.
i put it into an encryption folder
my 3.3ghz I7e 975 can smash that 512bit encyption with in a month.
i can crack: (in real time mode)
Rijndael 128-256
Tripple DES 128
DES 56
Blowfish 128
PK v2.04g

and you can delete it, a encrypted file can be deleted. it just means it cant be read with out being decrypted. from my perspective you dont know what your talking about
AES 128-256
