5 alijah mohammad January 27, 2009 at 9:10 pm

it is very self explanotory. you boot from disc, and it cracks passwords automatically. very simple my friends. very simple.

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?

7 dave March 5, 2009 at 10:43 am

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????

8 JOHN March 8, 2009 at 7:36 am

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?

9 Jade J'adore March 30, 2009 at 8:43 pm

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

10 scabb April 12, 2009 at 4:11 am

Vista ISO didn’t work on dual core, will not load default plug n play

11 matt April 29, 2009 at 10:58 pm

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 or dvd-r it doesnt matter it fits on both 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?

12 Ankit chauhan August 13, 2009 at 4:33 am

I think this ophcrack is not made for cracking win xp or vista password. It is a cd for fun only.

13 susan September 1, 2009 at 11:39 pm

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.

Which is why you use it to get the SAM hash, then crack the hash with a pre-generated list….

20 paarthaa October 22, 2009 at 9:01 am

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……..

21 Diana October 27, 2009 at 8:30 pm

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?

22 bimo November 8, 2009 at 9:33 pm

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)

23 biruk November 12, 2009 at 9:24 am

what are the infects of ophcrack xp or vista password cracker or recovery.

24 Guss November 19, 2009 at 3:08 pm

Table found

Is theer a way to crack the PW on Vista or not??
any help is highly appreciated, I don’t want to fomrat the drive at this stage

pls help

25 Duck November 23, 2009 at 3:35 am

Sort of the same problem here guys. I get two partitions and it wants me to select one. Every time it asks me to select a partition to crack, i type the extensive directory and it gives me some error about not finding it. and says press any key to exit. how do i tell it the Partition to crack? it detects 2 partitions for me. and neither seem to work once i type the extension listed above.

Reset /crack/hack/recovery windows password/admin password/ vista password with windows password Recovery tool 3.0

1. Log onto a computer that can link to the Internet. Download Windows Password Recovery Tool 3.0 from site:
for Windows XP, Vista, 2003, 2000, 2008 and decompress it on that PC. Note that: there is a .ISO file. Burn the .ISO file to a CD.
2.Get out the newly created CD and insert it to the locked computer. IT IS SHAREWARE.
3.Re-boot the locked computer and then follow the process of instructions. Just after a few steps, the old password will be removed.
4.Set new password:
Step 1: Open the “Control Panel
Step 2: Click the “User Account
Step 3: Select the account you wanna set a new password.
Step 4: Click “Changing Account ” and “Set Up Password”, then fill out the form as listed. Click “Create Password”.

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

on vista i am not sure yet currently i am using an XP machine when i get a chance i will test it on my laptop which runs on vista.

28 ved prakash sharma December 9, 2009 at 9:04 am

42 Phil March 14, 2010 at 12:48 am

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
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?

how can i convert live cd downloaded file into an iso file? plx

45 drew April 3, 2010 at 5:32 pm

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

46 Chuckles April 8, 2010 at 2:32 pm

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.

51 Nihaal May 13, 2010 at 8:00 pm

I had same problem, The trick is, to not use your windows/vista burning program. Get a different program, any, then it’ll work

52 Nihaal May 13, 2010 at 8:01 pm

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.

I had same problem. took me 15 minutes or so to crack then it showed “not found” I was like !!!!!

60 steve June 25, 2010 at 1:27 am

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.

61 dfsgdfsgdfsg June 25, 2010 at 10:24 pm

66 Marina July 29, 2010 at 1:21 am

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!

67 Righi July 30, 2010 at 3:39 am

Ophcrack is an amazing program if you can get it to work properly. I understand that many of you are frustrated that you can’t use it to crack your computers. The truth is you’re going to need a better table. If the password you are attempting crack isn’t simple, then you’re out of luck. Ophcrack requires you to purchase their complex tables for a hefty price. Try looking on pirate bay and other sites for special tables.

79 Vincent November 5, 2010 at 10:34 pm

The same thing happens to me after I access ophcrack and try to load a table in. I was able to get ophcrack to use bruteforce to crack one password (4 letters) but bruteforce only works for passwords less than 5 letters. Whenever i click the tables on top then click install on vista free then navigate to the location of the tables and click ok. the ophcrack exits on me. Any help on this problem would be appreciated.
Thank You

92 xXStric9Xx February 16, 2011 at 6:28 pm

You need to change your boot order in your BIOS. Change it to boot from disk drive. In the BIOS, the disk drive name is usually the actual name or brand of your disk drive. That can be found in your system info. Different pcs use different BIOS. Try pressing F2 or DELETE, possibly F10, you will have to figure out wich one gets you into BIOS. You will press this button repeatedly during start up. This should work asueming that the ISO was downloaded correctly and burned correctly.

107 VEGOIL February 5, 2012 at 3:58 pm

For the folks that get a boot error, you need to create a drivers disk for you drive controller drivers.
Hit F6 when booting up to add special drivers.
You can also use UltraISO and edit the ISO before burning and inject the new drivers into the correct folder then burn.

OphCrack does work on Windows 7. You must download the Ophcrack for Vista which works for 7 too.

Good luck!

you’re an idiot. that only works if you “already” have admin access

look at the dates. you’re two years later than most of the people

I get no results from Ophcrack Vista too. After waiting for about 15 to 20 minutes, it ends up with password not found. Is this because the version I’m using it on is the business version or is it just that Vista’s still too powerful? Do we need more tables or other methods?

112 Jerome Johnson February 22, 2012 at 4:57 am

I am using the live cd on windows 7 and it was able to find all the passwords except the admin’s, and i don’t know why. I need some answers. But it is really Good.

113 Erik March 12, 2012 at 9:02 pm

If the password is too complex you’ll need to get one of their paid for tables, the free version can only do so much. If you have a password such as ABCDefg12345, that is too long for their standard set. But if it is just Abcd1234 (ish), then it would be much easier and their standard set of tables should be able to solve it.

114 Erik March 12, 2012 at 9:03 pm

Which table set are you using, because I’ve been trying on 7 and I can’t get it to work, thanks.

115 Erik March 12, 2012 at 9:06 pm

Assuming you have 32-bit and your password isn’t too complex…I’ve been trying on 64-bit with my very long password :)

116 Erik March 12, 2012 at 9:07 pm

More than likely the password was too long or too complex, another set of tables would probably be good :)

117 Jaideep March 18, 2012 at 2:03 pm

Worked great for me! The funny thing was that it dint find the password i had set, but suggested another password that worked equally well!! Saved my neck! Thank you guys!!! really!!

118 informaticien March 18, 2012 at 3:25 pm

i rather like UBCD and password recovery tool !

ophcrack is nice but don’t work on several manufacturer brand …


119 Angel March 30, 2012 at 6:26 am

Ophcrack DOES work on Windows 7. For those that are having problems (computer just booting up to the Welcome screen) after you’ve inserted the Ophcrack CD, you need to change the BOOT ORDER in BIOS. It’s very, very simple to do. Just restart computer and press either, Esc, Delete, F2 etc. (whatever key your computer uses to enter the Set Up Menu. You should find an option for BIOS and somewhere in there you’ll find a tab that says, BOOT ORDER. You have to change the sequence so that the computer boots up from the Optical disk/CD drive instead of the hard drive. Make a note of the original boot up sequence on a piece of paper if you don’t want to make this a permanent change. After you save that the computer restarts on it’s own.

After you’re done using Ophcrack, you can repeat the same steps to change the boot order the way it was prior to changing it to boot up from the Optical Disk/CD drive. There are plenty of step-by-step tutorials online to do this and it’s easy peasy to do. I suck at using computers but Google is my friend and I figured this out on my own.

Question: So, I tried using ophtrack on a usb rather than burning it on a cd. Everything was fine up to the last step when it loads and cracks the NT Pwd. But, it doesn’t crack the password. instead, it just says “not found” in the NT Pwd column. Is it because my password is too complicated?- i remember that my password was a short sentence- like 15-20 words with no numbers. Is that too complicated for it to crack?

Also, on a sidenote- my computer has windows vista..

122 EK May 21, 2012 at 5:27 am

can you please answer my question below? I watched several videos and read several questions but no one ever mentioned my problem… maybe I’m not looking enough… please give advice??

123 vipcool7 July 17, 2012 at 7:02 am

There is no reliability in using ophcrack cuz sometimes it cracks the passwordword in win 7 and most of the times it doesn’t. So i would recommend KONBOOT which almost everytime opens the admin account wihout a password. And then you can easily change the password using command prompt.

124 Tim July 20, 2012 at 1:50 pm

All I get is a black screen after all the text, and it stays like that.

125 Marcel Rymenhout July 25, 2012 at 11:27 am

Hey guys i use ophcrack for win 7 32 bit but somehow at the half of the reading the disc(black window lots of letters) it stucks at a point say all ok Search something… can u help? this happens when i leave it to do the work automatically…however if i do it manual it’s hard for me ( 15y.old) any help???

127 Anonymous August 7, 2012 at 2:05 am

You cannot do that when the admin account is locked and is the only account.

128 Nerd August 7, 2012 at 2:11 am

If you are able to log on as admin, open command prompt and type:

net user (your admin accounts name) *
It will then allow you to make your own password.
ex: net user Admin *

If not, run it in safe mode and try.

I bought a vista special table from them, how do I install it since I’ve already burned livecd to my DVd-r. Cause it says that the table is 7gb and my DVD is only 4.7 gig. Do I need a dl dvd or what?

130 Anonymous October 6, 2012 at 4:29 pm

Make sure you have the updated version for windows 7. Microsoft changed the hashing method in windows 7 so any other version will not work

131 techmn October 6, 2012 at 4:34 pm

try getting the updated version. Microsoft changed the hashing method in windows 7 so the older versions of the program will not crack windows 7 passwords.

Will not work on Win7 pro 64bit – HP/Compaq 8200 Elite – boot fine, i can select graphic, etc text mode.
The Screen scrolls linux… then black screen and NOTHING.

Tried graphic mode, and text mode, same thing.

134 FTCnet December 16, 2012 at 9:23 am

.. Vista/Win7 version worked fine on a customers Sony Vaio W7HP for a 9-char alpha-numeric password

135 sure December 20, 2012 at 11:01 pm

for all you folks having problems getting it to boot from CD ROM – do this:
as the computer is rebooting – press F11 which forces it to give you a list of boot sources.
this will take a bit as it goes through regular BIOS checks etc. but no longer than normal ( just seems like it)
then you will get a list such as
Hard Drive

use the arrow key and move cursor to CD ROM selection and hit enter. it will then start booting from CD
As to what program/boot works best -there’s no way to predict in general. just keep trying until you win.

thanks to everyone posting on this, it really does help others who are in need.

136 yolodude December 9, 2013 at 10:08 pm

Hey, I downloaded all the files, but they are not working. Also, does this remove the password or just give me the password/ encoded password. Could you tell me exactly what I should be downloading and doing? thanks.

137 Groovus March 28, 2014 at 11:05 pm

I thought that I had forgotten my password for my Administrator account. It is the only account that I use on the computer and I wanted it to have a password. I tried to get in after I gave it a password but Windows XP locks me out asking me if I had forgotten the password.

I used OPHcrack and it came up with the same password I thought it was. I stopped the program that wanted to go on forever. When I try to login as Administrator on XP (SP3) it still asks me if I have forgotten my password, even while myself and Ophcrack use the same password as I likely entered to begin with. What could this be?
