Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a GTK+ Graphical User Interface and runs on Windows, Mac OS X (Intel CPU) as well as on Linux.
There is also article and more screen shots at Lifehacker:
Extremely impressed at the ease and speed with which the Ophcrack Live CD cracked my Windows admin password when I tested it out last a few weeks ago, I thought it might be useful to throw together a quick guide detailing how to use this powerful little utility.
Crack a MS- Windows 7 / XP / Vista password with Ophcrack Live CD
Whether you need to recover the lost password to a Windows account, you're looking to ensure that your passwords are secure, or you're a super l33t h4x0r, the Ophcrack Live CD is a pretty useful tool.
Does this crack vista passwords? I got a few of them that need to be reset but dont have the time to reformat them to get them working again.
yes u can crack vista password with it
how can i crack vista in Ophcrack Live CD
i got mine to work, when it shows you the two choices and everyone keeps typing them in where it says 0 or 1, dont type anything except for 0 or 1 and it worked for me on a Dell Studio Dual Core, thought i could help
required to remove password from vista machine
how creack computer account password
it is very self explanotory. you boot from disc, and it cracks passwords automatically. very simple my friends. very simple.
unfortunately, ophcrack didn’t recover any of my passwords… and the one that I knew was only 9 alpha-numeric chars. I was quite disappointed with it (even though the interface is nice)
i downloaded the Ophcrack.iso file and burn into a cd disc.
I did try to boot up the pc with the disc, but it seem not booting from the disc.
my pc did looking for a while on the disc and continue to boot from my harddisk.
Is there anything that i miss out?
I had same problem, The trick is, to not use your windows/vista burning program. Get a different program, any, then it’ll work
i used this OPH live cd with vista and its couldnt crack my password, my xp one cracked all the users, but vista didnt get cracked????
does ophcrack require a regular cd-r or a dvd cd? which is best? also, do i boot from the pph cd or put in at a certain time?
see u can ONLY use CD R, which pisses me off bcuz i have DVD R only -.-
I most definitely used a DVD-R and it worked wonderfully. Just set the write speed to the slowest that your program has and you shouldn’t have any errors if the version you have is clean. If it still doesn’t work, search around and download it form a different site than you used the first time.
once the .iso file is downloaded would I need to burn it onto the cd/dvd useing a burn image program or just copy/paste file onto disk? Thanks! -JJ
Vista ISO didn’t work on dual core, will not load default plug n play
hello,
i download ophcrack iso file and burn in CD by Nero sucessfully.
-i boot my computer from this cd
-the software works ok
- but i cannot crack the password
-plz help me
-send me the step by step by step procedure via e-mail
Hello,
I dont know it works on Vista, I tried several times but no password found but when i tried it on Linux, it works. so not sure if it is because of Vista or the program!
a couple questio0ns answered…
1. there is a special version for vista. just google search “ophcrack live cd vista download”
2.u do have to burn it with a cd burn program. i recommend imgburn
3.cd-r or dvd-r it doesnt matter it fits on both
4.to make sure it boots from disk do these two things
-make sure u burn it do a disk using cd burn program and not just copy-pasting files onto disk
-go into ur bios and make sure the order of boot puts cd a higher priority than hard disk
5.i think u have to install tables or something?
I think this ophcrack is not made for cracking win xp or vista password. It is a cd for fun only.
Can anyone pass me please the link to download the ophcrack livecd for widows vista? i downloaded ophcrack 2.3.1 but it didnt work. Please help me, I really need your help, I have essential information in the system I cant loose. Thanks! SUSAN
here is a link http://ophcrack.sourceforge.net/download.php?type=livecd
kernal panic – not syncing: Attemped to kill the idle task – this what I got on the post after selecting a mode with Ophcrack vista for Win Premium.. and downloaded the file twice and burned it twice.. got the same message..
oh yeah, i m using a virtual machine… it shouldn’t matter.. for my xp ophcrack Cd works great
Hey with the Vista verson 2.3.1 …. when i load the ISO cd it comes up with a comand promt box which requrestes you to enter the portion you want to crack… what are you ment to do here because whatever i enter it comes up with an error… and then it loads a desktop screen with Slitaz…. is this ment to happen? is this happening to anyone else
Omg that happened to me too, how do you fix it or is the file from website broken ?? Please help
um… the way ophcrack woks, IT CANNOT CRACK or FIND VISTA PASSWORDS, NOT POSSIBLE, EVEN WITH THE VISTA LIVE DISC
Which is why you use it to get the SAM hash, then crack the hash with a pre-generated list….
i can not get this to work on my vista can anyone tell me anything else i have info in here i can not loose
If you forget the administrator’s password but still can log on Windows with other user names that have administrative privileges, you may follow the instructions below:
Right click the computer icon on your desktop, select Manage, find Local Users and Groups, unfold Users folder, right click Administrator, click Set password… in the menu comes up. Click Proceed in the dialog, in the pop-up, enter a New Password and confirm it. Your administrator’s password is successfully reset.
Guest account may help to log onto Windows, but it has no privilege for you to do the above to reset the administrator’s password.
If you forgot all user passwords and failed to log onto Windows, there is no other way but to format the OS and reinstall Windows, or resort to sort of software tools to remove the password and log onto Windows. These programs cost some bucks, but are worthy and better than to reinstall the OS causing consequences. The most popular programs are Windows Password Reset 6.0 etc. Generally, these programs are easy to use though turn out to be a scary command prompt to newbie. But do relax and you can fully manipulate. Let’s take Windows Password Reset 6.0 for example. You prepare a blank CD, burn the program onto the CD, boot the locked computer from the CD, come to initiate the program, locate the user name, and proceed to remove its password – all are at ease.
two days before i unfortunately set my password in vista……but i can login into my laptop with those passwords….and i heard about ophcrack and tried for cracking the passwords….but the result i got was “not found” in “nt pwd” column….. what can i do now……..
I had same problem. took me 15 minutes or so to crack then it showed “not found” I was like !!!!!
I burned OPH 3.2.1 Vista Live to DVD and booted up. It ran through it’s processes and after about 20 minutes, none of the 3 passwords on my machine were found. What puzzles me is that I KNOW that 2 of the 3 passwords are simple (short alpha/numric only, no characters.) So, is there something more that I need to be doing besides just running the program?
Yes, live cd vista uses tables or should i say table– vista free table. It can’t hack more than basic passwords containing a charset (403cf58178d7272a48819b47ca8b2e6b) password length unk. The vista special table can be downloaded it contains a charset (0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ) password length 7 crack or charset (0123456789abcdefghijklmnopqrstuvwxyz) password length 8 crack but this will cost ya $. Hope this helps.
what are the infects of ophcrack xp or vista password cracker or recovery.

hi everyone i see you are having some issues using ophcrack on vista i had a few issues also i fixed it some of you dont seem to have downloaded the table the table is not downloaded on install you must google it and find a talbe to download it will come in a zip file you must download WINRAR from google then extract the table file to a folder on your desktop then open ophcrack click on tables, install, and find the file highlight it then click ok
once youve done that the table will be recognized by ophcrack and then click on “crack” and it will start going through the table.
if you cant even login you dont know the password you could try the live cd or if you have a graphing calculator there is a way to crack the password with it you need a computer hook up though and a small program must be installed i am pretty sure on the calculator itself
this is on youtube

Hey i have a question, i used ophcrack vist live cd on my vista computer, but when it was dont searching, it said the passwords were “Not found”. I dont know what to do now. anyone know plz plz email me:(
hi to all ophcrack users! everytime when i try to boot my pc from the cd it works. but then ophcrack offers me 4 possibilities: 1: Ophcrack Graphic mode – automatic
2: Ophcrack Graphic mode – manual
3: Ophcrack Graphic mode – low ram
4: Ophcrack Text mode
which one of them do i have to take, that ophcrack starts to show me the passwords of the users as seen on all the youtube videos? everytime i click at the first for example there appears a brown screen that looks similar to the windows start screen and its written “ophcrack live cd
running on slitaz
os”
on it. in the middle you can see a comand promt box which requrestes you to enter the partition you want to crack… what are you ment to do here because whatever i enter it comes up with an error?
Please can anyone help me?
Most people like Graphic mode (Either one, automatic bttr for beginners, iguess). But if graphic doesn’t work for you, sometimes you get error, use text mode.
