Have you ever tried to log into a Windows computer for a few minutes and you finally realize that you forgot the password?
There’s a way to crack the password and it doesn’t involve reformatting and reinstalling Windows.
The solution is called @stake LC4 (formerly L0phtCrack), however since Symantec stopped development of L0phtcrack, I’m going to let you in on a program called LC5.
Just like L0phtCrack, LC5 attacks your Windows machine with a combination of dictionary and brute force attacks.
LC5 can crack almost all common passwords in seconds. More advanced passwords with numbers and characters takes longer.
The main purpose of the LCP program is user account passwords auditing and recovery in Windows NT/2000/XP.
I haven’t tested it against Windows Vista yet, so I’m not sure if it will work. Your mileage may very either way.
How it works:
Windows NT, 2000 and XP passwords are stored as encrypted hashes. LC5 attacks these hashes with hundreds of passwords per minute.
Eventually the correct password will be sent and then displayed to the screen.
Good intentions:
- System administrators can find weak passwords within minutes. Sys admins can then change the passwords to make them more secure.
- LC5 can be used to access computers of users who forget passwords.
- In companies, it can be used to access computers of employees who have left the company.
Bad intentions:
- Hackers can use LC5 to sniff passwords over networks.
- Hackers can install this application onto a primary domain controller and steal hundreds of passwords within minutes.
Please note that I am not the author of this software. Be advised that if you use this software, you do so at your own risk without any warranty expresses or implied by Geek With Laptop.
Download LC5 (v5.04):
- English version (with installer) – 2.29 MB
- English version (without installer, ZIP) – 1.86 MB
- English version (without installer, RAR) – 1.66 MB
Software License: LCP is a freeware program. The program may be distributed under condition of saving all files contents and structure of installation package.

Interesting article. When I used to work in a large advertising agency the staff were often shocked when they found out that the IT staff could easily hack their passwords. They seemed to think they owned all the info on the company owned computers that they used.
This sounds pretty interesting. We used a similar software at my tech support job a few years ago. It is funny how people never consider that their computers aren’t as secure as they think they are!
Thanks! I’ve been searching Google for a while now, trying to find direct downloads of an LC5 trial.
However, the program you provided isn’t actually LC5. It’s similar to LC5, but it isn’t from @stake (now part of Symantec). I think the proper name for it is LCP or LCP 5.04. Nevertheless, I want to thank you for introducing me to this FREE program. It’s definitely better than the last version of LC that @stake created.
This post rocks!

Simpler solution is ERD 2000, boots up on a cd rom, one click password reset from outside of windows, no need to “crack” the password, which can take a while if it’s a complex one. We use it at work all the time, takes .25 seconds
I’m guessing the above method is just for XP Professional, most XP Home editions are very easy to ‘un-lock’ as I’ve found, (I repair PC’s as a part time job and I found this method when a person who shall not be named forgot their login password)
As many of you will probably know, the Administrator account will not appear on the Login screen of XP Home, and most (non-technically orientated) users will not even be aware it exists, but when loading the computer, if you enter safe mode (By pressing F8 during startup), the Administrators account appears on the login list, you can then easily log into this account (It will usually not have a password), when logged in go into Control Panel, and then users. Once in here click ‘Change Password’ for the user that is ‘locked-out’. If you leave all the fields blank and hit ‘Ok’ then it will remove the password and allow the user back in again.
Again this may be ’staring-you-in-the-face’ kind of obvious for most users, I just havn’t seen this method posted anywhere before, thought I’d share

Can I use this safely on my computer, if I’m the only one who knows about it? Do I have to worry about hackers on the Net?

Matt, if anybody has encrypted data on their computer using windows security, you just made recovering it a task that would take a team at the NSA an entire week to accomplish. Just FYI.
That’s cool, thanks. Im going to make up the insane-est, hardest password ever just too see how long it takes to crack. Got an over-under on it?
An even simpler solution, that is FREE and open (unlike ERD) is:
Offline NT Password and Registry Editor , located here:
http://home.eunet.no/pnordahl/ntpasswd/
Bootable (live) image, removes Administrator password. Works like a charm.
Note: If the user has used the Encrypted File System (EFS) you won’t be able to read those files, but should be able to login as them with no problem at all.
ERD blows if you’re trying to maintain an anonymous profile. i’ve spent some time messing around with ophtcrack and it is awesome just do a google search for it. i used it during my last password audit of my organization.
Would it be easier to use knoppix to access the pc content as long the bios is open to run the live cd?
Hash “marks”? You mean like “######”? Wrong kind of hash…
This doesn’t work with Vista. Win NT/2000/XP by default used the weak LM hash for compatability in conjunction with the strong NTLM hash – which is much harder to crack. Vista uses only the NTLM v2 hash. Its crackable but I doubt you want to sit around and wait for it.

About the no-password Administrator account:
You don´t have to enter safe mode; is you press Ctrl+Alt+Del, release and press again Del (Ctrl+Alt still pressed) at the normal mode login screen, it takes you to the Windows 2000-like login screen, there you can type in Administrator and leave the password blank… Easier, is it not?

OPHCrack is a Diagnostic tool I use regularly for cracking windows passwords, it’s a linux bootcd that uses a similar cracking method as LCP. I like OPHCrack because it cracks most Windows OSs (2000/XP/Vista/etc..). Also because it’s not changing anything it doesn’t lock you out of your encrypted files. Usually only takes a couple minutes to crack and it lets you remove doesn’t have to deal with windows at all.
Try it, I think you’ll like it…

It should work on vista too because the SAM file is still in c:\windows\system32\config\SAM and its still the same encryption.
I downloaded LC5 and works great. How do i use it to crack a password on a computer when I am not logged in on that computer?
Thanks for the tool
Hi I’m trying to crack a window vista password.i used ophcrack and i got this : JR:1003:aad3b435b51404eeaad3b435b51404ee:37c088d8d1e18c245c25483c5fd5314d/empty/:
But i cant crack it.Shouldnt be a long passwrd but maybe got some number.i used cain&abel and johntheripper but nothing.is it possible can be uncrackable?
I’m Just wanna ask if i could do this on a school computer?
i’ve used the ophcrack on 2 computers and it did not work, got error saying could find executable rhcommand. so if i download the lc5 do i have to burn it to a disc or how does it work?? i have my 15 year old daughters computer i want to check without her knowing it. but i can’t login into it she has a user password on it??
What if the computer has the administrative passworded in safe mode? Am I out of luck? Please help. Thanks
I’ve tried to crack the NThash password on windows vista using ophcrack. Does anyone know how to make it work? I’ve forgotten my password, right now im trying everything, even making boot disks to try to overwrite it.
i have been a comp with an admin password, but the passwork won,t login anymore (just switched on the machine and the same password won,t login) how do i reset or recover password from a non admin account – which cannot allow me to install any programs
Could any one help with product key for Microsoft Office 2007.
hey,
i love the post.
but how do i use the program?
i dont see any image anywhere to put on a cd,, and i downloaded and installed the program..
You guys are mostly all morons.
LCP works great.
The only problem is if you trying to find a admin password from another pc than the one LCP is installed on.
To do that you have to copy the SAM and SYSTEM file from the other pc.
To do so I boot the other pc with a Linux boot disk which gives you total access to all files on the drive. Copy SAM and SYSTEM to a USB drive and then go the pc with LCP on it and crack away.
Took about 5 minutes to find the admin account username and password on a work pc joined to a domain.
Can any one help me with cracking a password for Windows Vista?
OK my parents changed my password, which is really annoying, and I’m trying to get it back. My computer is Win XP and I tried the ctrl+alt+del+del thing but it says it can’t do it because of ‘account restrictions’. For some reason the downloads aren’t working, either.
Can anyone help?
PS: to the mom trying to look at her kid’s computer, LEAVE IT. I felt like smashing my mom when she invaded mine.
LCP works fine, and yes most of these posts are moronic. Like Tasha – so you don’t like your parents controlling things that are their responsibility (like you)? What about the computer they probably bought for you? that you use with the electricity they pay for? that’s in the house that they provide you?
Play by their rules, or move out when old enough. Else shut up and quit crying.
By your argument, the governments should have full control over the people they are responsible for. And we know how well, historically, totalitarian governments have fared (and how well they’ve been liked).
There’s a difference between controlling and being responsible for.
Although this isn’t really the proper place for that kind of discussion. This is a forum for computer problems, not criticizing others’ opinions. So tell me how to get around this, or, um, shut up.
How does this software work (LCP5)? I cannot get pass the login screen. My laptop does not have a CD-rom drive so I used my flashdrive. When I connect my flash to the laptop nothing happens. In user accounts I turned off the guest account and left only the adminstrator account active. Unfortunately, I forgot the password and am not able to get pass the login screen. HElp!! Quick Please!!!
Download Hiren’s BootCD 9.5. boot it, then choose next. Then choose the one that says passwords. Then choose the one that says active…. …xp/vista. Then choose which drive. Then select the account. Then press Y to CLEAR there password. i work at a computer place. i get into computers with passwords all the time using this method. Or you can use OPHCRACK. It actually TELLS you the password. but it does take longer than using Hiren’s BootCD and just clearing it.
If I use Ophcrack on my computer,will it harm it in any way or change any settings?
No. It will NOT harm your computer. I have not succesfully cracked a windows vista password. I have cracked xp passwords several times. So now I am forced to just clear them using Hiren’s BootCD. My disc is very old, so maybe I will download another iso, then burn it. Oh well. But the answer is NO, it will not change anything or harm your computer. It just finds passwords and displays them
Hi guys, I am trying to help my gf break into her bf’s facebook. Can anybody help?
Thanks guys, what would the world do without (GEEK POWER) your help is well appreciated.. Good job!!
Question: Is this boyfriend local? If so, if you can get access to the computer he uses to get on the computer, all you have to do is go to download.com, search for keylogger, and download home keylogger or family keylogger. Everything he types *username* and *password*, will be recorded and only you will know its there. A special combination of keys will bring up the hidden application and display everything he has typed. I have used home keylogger for when people I don’t really like use my computer, i have ALL there information. HAHAHA.
Claudio: Thanks
I had a friend let me borrow his computer and he had 4 passwords on it. (windows XP) I used the OPHCRACK (FOR XP) and it found all four passwords!
am stiil confused actuallly how it works do you need to first install it or you have to move with the cd containing the software please reply and how can i get it
derricklilldude
Dude, just click on my name and one of the links there will be for the ophcrack cd. there are 2. one for vista and one for xp. you don’t install anything. download it, and burn it to a cd using PowerISO. There are other things you can use. But I HIGHLY recommend PowerISO and burn it at 4x. All my linux distros have had errors going any faster than 4x. And its not my computer. I have a new DVD writer, and I have a couple other computers. This is my hobby. This is what I am good at.

I posted this twice because the first time i didn’t click the # icon under dudes name. And I wanted him to get this comment
To crack passwords
there are 3 methods: dictionary, brute-force and cryptanalysis.
LCP, the Russian equivalence of LCP5 (not available anymore) does not use cryptanalysis.
I read much confusion and amateurism in the posts above. Most the writers probably cracked an EASY password from their admin. account, on the their stand alone machine.
You can get some knowledge here: http://www.lcpsoft.com/english/articles/passwords.htm
If you want effective tables to use with Ophcrack, they come at a price (99$). However with effective passwords, you will need much more than that.
You will also need to cover your traces, if you try any methodes. That’s maybe something your wife doesn’t know, but your IT does
admsupport
Thanks for that link. I read about 90 percent of all that. I now know more than I did before about SAM’s and passwords. I can highly recommend other people to click on admsupport’s link. It provides instructions on how to keep your computer out of people like me’s, way. Cause even if you set a bios password to keep me from booting from a thumb drive, or cd. I will STILL get past it. I know to much about computers for someone to keep me out of there account.
is this LC5 can be used to crack the password of a system without loging into it???please reply….
josh i still dont understand you please
josh i think ineed direck lectures from you i you could posibly teach me this whole stuff directly(derrickililldude@yahoo.com,+256703030403)thanks derrick
xeda…
No. You don’t have to log in to the computer at all to crack the passwords. Just boot from the cd. If its a Dell computer, immediately start pushing F12 when you boot the computer and choose CD. If its anything else, it should boot from CD before it boots from the hard drive. And you can leave it alone once it boots from the computer. Put the CD in, turn the computer on, and about 20 minutes later (sometimes longer, sometimes shorter. Depending on the strength of the password), and you should be able to see the passwords to all the accounts on that computer.
derricklilldude…
what do you not understand? I first need to know what you need help with. If you click on my name, I have a link in my drop that takes you to the OPHCRACK page. Download it, burn it to a CD, then put it in a computer. Or download Hiren’s bootCD if that’s easier for you. Just click on my name and it will be there. You boot it, click next, then passwords, then active password changer. It clears all the passwords on the computer.
I tried L0phtcrack cd but it gave me nothing. I have prepared a password in Administrator, but L0phtcrack has seen it…
What a tolld is it?
Hello Josh,
Can you explain how to infiltrate or hack into a laptop or desktop that has the BIOS password set? I do not understand how it can be done; I have looked into the matter before, but I had no luck finding a solution on how to reset or remove the BIOS password, as it immediately asks for the BIOS password once you reboot the computer.
Hi Josh,
I downloaded ophcrack but there is no ISO file there (at least none that my computer can see) to burn to a CD. Did I do something wrong?
John,
When you take the battery out, get something metal or that can conduct electricity and touch the 2 ends that the bios battery would normally touch. When the power is off, make a connection and turn the power on and then off. I am not sure the EXACT time or step it does it, but it shorts the bios to default settings. I set a bios password and it pissed me off because when I typed in the password, it said it was wrong and it wasn’t. So I tried the ultimate test and it worked! I swear to god I have successfully done it. Good luck. If you perfect it, or know exactly when it shorts the bios, let me know. But like I said, it worked for me.
bcm,
You downloaded it from the sourceforge website and it wasn’t an iso? That makes no since at all. What are the last 3 letters after the . ? example, “setup.exe” What comes after the filename?
Download it again, and then goto this link http://drop.io/usefulstuff and download the Portable PowerISO. Nothing to install, I swear. You can run it from a thumb drive. Its awesome. Just a single exe. Open the .iso with portable PowerISO from that link and burn it at 4x. Any faster than that and your asking for errors. here is a trimmed ink to ophcrack http://tr.im/ophcrack
if you need any help, email me at mailto:hidd3n1-geek@yahoo.com or message me on here. (sorry if that “mailto:” doesn’t work. just copy and paste the email address)

how do i reset administrator password for windows vista
I recently had a problem with my girlfriend hacking into my computer. She got the passwords for my yahoo, hotmail, aol, and tangowire accounts. I have read the above comments and I know how to prevent it now, but what I don’t know is how she did it. Does any of her actions leave a trace? How can I hack her computer without leaving a trace and without downloading software that might give me a virus
Hi Josh,
Can you please help me with a simple way to get the passwords to any acct and cover my steps in the process. I don’t really know how my girlfriend cracked my codes as I don’t see any software on my personal laptop that should not be there. I am not as computer savvy as some and I may need a little one on one help. But I need to prevent this thing from happening again. Also, I need to know how she did it
Hi worried,
That really SUCKS! But I would have done it… I am a noob hacker. Do you use firefox and click save password? It’s as easy as going to Tools, Options, Clicking the security tab and clicking Saved Passwords. All your passwords are in plain sight for everyone to see. If you use Internet Explorer and save them, it can be done to. As well as chrome. You can set a master password in firefox so that some peeping tom has to put in the master password for all the other passwords to be viewed. I suggest you set a master password. Its in the same Tools, Options, Security area. It will kinda suck because you will have to put in that password everytime you start firefox. Hope that was some help. Feel free to explain more, or just reply again. Merry Christmas.

Daniel,
How in the world did you get all your text upside down? HOW?! That’s cool. I almost had to flip the monitor upside down. Anyways, I haven’t used LC5. I know you won’t get into her myspace. Just dowload a keylogger from Download.com and have the computer record all her passwords for you!
Are you gonna tell me how you got your text upside down?
hey Josh thats cool, yeah i’ll try that keylogger thing.
And for the upside down text, i used a javascript program to flip it. The Javascript program converts english letters to unicode characters and symbols that look like upside-down backwards text. I like writing messages and stuff on myspace and wherever else i choose to confuse people… Its hilarious.
there’s a link for you Josh… enjoy
So I ran the Live CD for OPHCRACK, passwords not found. Then I bought the tables, but am confused on how to use them.
Do I start the target computer with both the Live cd AND the USB stick that contains the tables? Why can’t I just put the tables on the Live CD?
Also, each table has a .bin, a .index and a .start. What do I need to have on the USB stick (or the Live CD)?
I received a sony vaio laptop with windows xp professional from a friend who is in desperate need to have me help him. His girlfriend locked him out of his computer. I tried the safe mode deal but the password screen came up. I am downloading the ophcrack xp on my computer to burn it on a disc. Am I so far doing the right thing. LOL ( p.s) I was really impressed with the intelligence of this site. Everything made perfect sense when you each explained your methods.
very brilliant.I must ask does this work for accounts? u know like um..lets say i have a laptop right? and i want to hack its password do u know what to do to get it? because i have a sister who has a laptop that she doesnt need and it has very good graphic card so im trying to log on her laptop to play the games i usually play but i cant because i dont know her password,anyways if u know a way for this please email me at jrnaruto1@hotmail.com thank you very much =)
Kimberly and Timberlake. Read over this forum and all the comments. I have explained how to do it several times. Please do a little reading before you ask the same question everyone else does. no offense.
i have a laptop that when i turn it on all i get is a black screen with a little lock symbol with a space where i need to enter a password but i have no idea what this password is. this stops me from even getting to the windows start up screen. i dont suppose anyone can help on this because i have no idea how to fix it, i’ve had people say i need a reset password for it?
@cherelle, its a bios password. Open a compartment on the back of the laptop and pull the battery out. Then get a screw or something metal and touch the 2 pieces of meta together that the battery would normally touch. Hold it there. Turn the laptop on and then off. It SHOULD reset the bios and that password is history
so after all those posts.. which one would be the simpler, easier way to unlock my computer if i cannot log onto it in the first place. how do i get this applications to work (for us that are not as tech sabi as you)
how do i download n burn the ophcrack for xp
i cant get in my computer cuz it has a pasword
HI I NEED HELP PLZ
Ricardo, what do you need help with? I have noticed that most people on this site ask questions without reading all the comments. How am I supposed to help people that won’t help themselves?
Hey Josh … thanks for all the help you are giving these guys , its much apreciated..
Thanks admin! Its nice to get compliments and stuff. Are you really the admin? The admin of this topic, or this site all together?
Why do people freaking ask how to get in a computer when I have wasted time typing the same thing over and over again, just to have someone else ask it again. Do people not do a little research first? All it would take is some scrolling and reading and poeple should see all the links and comments I have left.
Hi Josh yes I co own the site with Vlad the brave , see the about us page, your doing great keep going ..
i just burn the ophcrack to a cd n put on my computer n it didnt crack da pasword
i just burn the ophcrack to a cd and put on my labtop n it didnt crack the pasword
If the password is more than like 8 characters and has special symbols it will NOT crack it. You will need to purchase extra rainbow tables from the OPHCRACK website. They are like 99 bucks. Or if you can find a free torrent with the XP or VISTA rainbow tables, you could use them.
Download Hiren’s BootCD 9.7 from http://tr.im/hirens and boot it. If you choose next, then something that has XP/Vista password…. You can choose that, and it clears the password. And it doesn’t fail. It has always worked for me! Good luck. If you are trying to get into someone’s computer without them knowing, don’t clear the password. That will be very suspicious. I am here if you need anymore help…
Is there anyway I can get the password of yahoomail account.
Besides installing a keylogger on your computer (download.com), I don’t think so. If you know there birthdate and secret question’s answer, then you can reset it. But they will know because they won’t be able to log in. Only you will…
Best bet, install a keylogger and get them to sign in using your computer. I have done this. Its a mean method, but hey. They were talking about me behind my back and I wanted to know exactly what was being said. Its messed up when someone uses your laptop to talk bad about you.
Most antiviruses will destroy and delete the keylogger.
Greetings,
Initially pertaining towards the relevance of the predisposed article above the comments remain in the realms of utter entertainment; LC5 is as useless as rainbow tables amongst these contemporary times; alas OphCrack is
I think my boyfriend is cheating on me he wont share his password even though ive shared mine and he always wants privacy when he is in on his computer. So i followed the advice on this site downloaded ophcrack, ran it on his dell computer but i guess the password is too strong since it couldnt find it. Maybe i will buy the extra tables that are mentioned for 99. So my question is if he logs onto his pc will he know that ive tried something, some sites have said it doest make changes or leave footprints but when ophcrack ran it seemed like it was coping files for a long while and then when i it didnt work and i took the CD out it only seemed like it was removing files for a short while. Could someone help me with this question?
@Joann,
NO! It will not leave any traces behind. Sorry his password was bigger than the free OPHCRACK can hack. I have a 10 digit password on my windows because I know that free OPHCRACK will not be able to hack it. If you purchase the 99 dollar tables and it works, PLEASE be sure to let us know. You could always download Hiren’s Boot CD and just clear the password. Here is a link to it, http://tr.im/hirens. That site has the newest CD. And I have cleared several passwords that were to hard for OPHCRACK to handle. (I worked at a rental place for computers) Only problem is, you won’t know what the password was, he will know you cleared it, and if you do a system restore after clearing the password, the password will come up again.
Need any more help, feel FREE to reply back. Enjoy.

hi,can somebody tell me how to hack windows vista user password?
@Jammy,
No offense dude, but did you not ready ANY of the gazillion comments above? Like two comments before yours I had links to Hirens Boot CD and links to “OPHRACK”. Why don’t you help yourself before you ask for help… I have been through this so many times. I am not trying to be mean, but you should really read a few comments before you ask a question that has been answered so many times on this one site…
Download the VISTA version of OPHCRACK. (google it or click one of my links from previous comments) If it doesn’t find the password, just use Hiren’s Boot CD and CLEAR IT. (just boot from the CD and navigate through the menus.) Its really easy. You just need a CD burner, or a computer that supports booting from USB. OH!, you could use UNetbootin. It has an option to download OPHCRACK and it automatically puts it on a thumb drive and makes the flash drive bootable. HAVE FUN! HAPPY CRACKING!

HEY YOU ALL! There is a new OPHCRACK CD! Ophcrack Live CD! You HAVE to download the Tables!
Ophcrack Tables!
The Ophcrack CD is not going to crack passwords by itself! They changed the way OPHCRACK works! BUT it was for the better! The OPHCRACK ISO is going to be roughly ALMOST 500 MB. So that is gonna have to go on a separate CD. I would strongly recommend downloading the 703 MB Tables! (Don’t worry, after you extract the tables, it will weigh in at exactly 701 MB and PowerISO burned it to a normal CD-R with NO errors!
You can download the OPHCRACK ISO, burn it to a CD, then put the tables on a Flash Drive!
I burned the Ophcrack ISO and burned it to a CD. Then I download the XP Free Fast (703 MB ZIP), extracted the ZIP to my desktop, then I burned the tables to an ISO.
I have 2 DVD Writers in my desktop. I put the bootable Ophcrack ISO disc that I burned in tray one, then I put the tables that I burned onto a CD in tray two. I turned on the computer and it cracked the passwords that I use to log into windows in under 2 minutes. Granted the passwords were simple and only numbers!
If you need help, you can comment on here or read – SourceForge.net: Frequently Asked Questions – ophcrack. (I figured out how to properly burn the tables at that link!) Just extract the tables, then make a folder called “tables’ on your CD, then make 4 new folders and label them “0″, “1″, “2″, and “3″! So when your CD is burned, there should be ONE Folder “tables’ with 4 folders inside the “tables” folder! Those four folders should be labeled 0 through 3.)
Here is how my CD looks,

Trust me, if you look at how I did it in those pictures and then you copy all that onto a CD or a Thumb Drive, you will be cracking passwords better than the old OPHCRACK ever could! Because the tables are on a seperate ISO instead of the tables being on the same disc that the bootable linux is on! And this time around, you can browse the web using Firefox and delete files that have viruses or files that can’t be deleted in windows!)
Sorry, I didn’t get a chance to edit that and make it look really good! It’s 1:45 AM here in Tennessee and I should be in bed! I am really tired. I am just excited about the new Ophcrack CD and thought I would show you all how to do it correctly. Seriously, i wasn’t sure what to do with the tables after I downloaded them. And I even labeled my CD “Ophcrack XP Tables – 1st Try”. Because I wasn’t sure if I did it correctly. Just booting the 412 MB ISO is not enough to crack passwords. You will get an error message saying “No Tables Found”. You HAVE to download the tables and put them on a cd or removable media like I showed you all how in my last comment. Your CD or Thumb Drive should look like how mine does in the pictures I posted above….
I hope this comment and my last comment helps people out. PLEASE COMMENT…
Again, sorry for not editing my comment perfect. Its really late, my brightness is down all the way so that my daughter doesn’t wake up from the light, and I am tired. I didn’t mess up, but I didn’t add quotations and stuff properly. Oh Well, I really hope I helped someone out there and if i did, please comment!
Josh, you are a legend. Thank you for all your outpouring of knowledge.
Three Cheers For JOSH!!!
Hazzuh!
Hazzah!
Hazzah!
Another update!
For some reason, I could not crack passwords using just the Ophcrack CD and not adding the additional tables. But I tried it on another computer, and the Ophcrack CD loaded some very small tables and started cracking passwords. So it worked on one computer without additional tables, but didn’t work on my test computer without additional tables.
Either way, I Highly Recommend that you download the XP free fast (703MB) tables and extract them to a Thumb Drive or Burn them to a CD if you have TWO disc drives on your desktop. If you stick with just using the Ophcrack CD by itself, you risk not being able to crack passwords because it doesn’t work at all (like in my case) or the password is to hard for the “Free Small” tables built into the ISO to crack.
IF your trying to crack Vista, you have much bigger tables to choose from (UP TO 135GB FOR TABLES! That’s crazy!) But it works the same way. download the Ophcrack For Vista ISO. (The ISO is 492MB, so download the And you might want to download the additional Vista Tables just to be safe.
If you play it safe and always download additional tables, you lessen the chance of not cracking a password. Because there is nothing worse than trying to get into a computer with a possword, and it doesn’t crack the password because the tables that came with the ISO weren’t enough.
I did not succeed with this tool. Then i reinstall my Windows.
Ok @Bigbx, that is unfair. Because that is the easiest, simplest way of fixing a computer (or if you forgot your password) but for people like me, I get pleased to see the persons password, type it in and see there desktop.
Hi,
Question… I bought a secondhand Philips NAS, I don’t have the username and password for it, and the reset option to factory settings fails. So I can only use it now to store data and can’t make any changes..
Is there a way to crack the username and passw? Ive been exploring Pentoo a bit, to see if there’s a way to do it from another computer on my network, but sofar nothing.
Thanks in advance.
Hello Beertje,
I just found myself in a similar situation where I needed to get some data from an old laptop that I have not used since 2002, and did not have the forethought to write down my username and password. Duh! Anyway, after spending 2 hours putting in different user/pass combinations, I did a search for password cracking tools. I happened upon one called Ophcrack. You can actually download LiveCD, which is a CD image that you can burn directly onto a CD. You then put the bootable CD into the computer that you need to crack (make sure to set to bootup from CD). It boots up and runs automatically! It gives you all of the usernames and corresponding passwords in 5-10 minutes. Sweet! It is extremely simple and free! I used the XP version for Windows 2000, but they also have a Vista version. I am so excited that it handed me all the info I needed on a platter. Very nice! Good luck!

Forgot your Windows password? Don’t worry.
Download Windows Password Reset from this http://www.resetwindowspassword.com
Install this. Run the application and make a Bootable USB drive. It’s very easy as this software have wizard based interface for that. Just follow the manual.
Now go to the setup screen of the affected computer and set the 1st boot device to USB. Stick the USB drive to the computer and restart the machine. Once your machine boots through USB follow the instructions on the screen. You will get the details in the user manual of Windows Password Reset.
Hey Josh. I’ve got a problem and I see your the man 2 ask 4 help. I’m not computer savvy guess I’m kinda slow whan it comes 2 them but I’d like 2 learn. Ok now my problem I have a winbook laptop with windows XP professional installed but since I haven’t used it in a while I forgot my password, I read all the comments above but I can’t seem 2 get around it please help thanks
Ok poetic, I hear you loud and clear.
Step 1: Download Ophcrack. (The Live CD)
Step 2: Burn the ISO to a DVD. (Download any program that will burn an ISO to DVD from this link, Click Here. (I personally like BurnAware *its a really simple program*!) Ashampoo Burning Studio is better, but you might like the BurnAware interface better. Burnaware can be downloaded here, BurnAware Professional BURN AT A SLOW SPEED. I recommend 4X for no errors.
Step 3: Put the CD in the computer and then restart your computer.
Step 4: Choose default stuff. I think if you don’t click anything, it starts the way it should.
Step 5: It should find the SAM profiles on the computer automatically. If you see a screen with all of the Logins on your computer, you are getting somewhere!
Step 6: If all else fails, clear that freaking password! Download Hiren’s Boot CD 10.0, burn it, and boot your computer with the CD in the computer. Its got quite a few menus, but in there somewhere, you will find active password changer and it will clear the password from the computer.
Any more help, feel free to ask.
Damn! Josh you are the shit thanks a lot for your help I downloaded the files but managed to remember the fucking password LOL! Well I just wanna say thanks 4 the help your the best!!!
Hey I am a desperate handicap mom of 2. Born w/out my limbs. I’ve had sdome surgeries in these last years that my mind hasnt been as ‘bright’ as it use to be.

Even admin one, grrrr Anyways, i have the boot up cds but when i put them in the compter that i need passwords for, I restart it hopeing the cd starts, nope goes back to windows welcome screen login screen, jeez can you tell me how to get it to read the cd before opening the windows lkogon screen please?
Thank you!!
Sorry Beverly, I have been sick and I got your comment a couple days ago, but I could not reply. Again, I am sorry.
You might need to hit F10, F12 (if its a dell, that will work!) or F1. Some computers do NOT boot from CD without you going to the BIOS and changing the boot order. It could even be F2. Just keep trying… Try F12, it that doesn’t work, try F10, if that doesn’t work, try F1, if those don’t work, try other combinations of F1-F12. It could even be the ESC key! One of those will get you into your BIOS where you can change the boot order. Make the CDROM the first option. I hope this helps. Please tell me if you make progress or if you need any more help.
it should be F8 btw. i have been wanting to be a hacker but caz its still too much for me to learn, do anyone of you had some opinions or comment for me? i will be absoblutly greatful. thx in advance
very good!
BTW, there is another good solution.
It’s very easy and useful to reset local administrator and user passwords on Windows Vista system.
Get started with the download – 3 simple steps:
Step 1 – Download (http://www.windowspasswordsrecovery.com)
Step 2 -Burn your Windows Password Recovery Tool 3.0 CD:
To burn your CD, you’ll need a blank CD-R and the .ISO file of Windows Password Recovery.
Step 3 – Put in your newly created CD and remove your Windows password.
Hope it helps.
As far as I know , there are two main methods to solve the windows password problem as follows:
1st Method:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it’ll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from \Control Panel – User Accounts\.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.
2th Method:
Windows password Recovery software:
for example:Windows Password Recovery It is easy and convenient to use.
http://www.windowspasswordsrecovery.com/index.htm
here is the methods I know.
The first thing which you check if you forget login password. When we install Windows, it automatically creates an account “Administrator” and sets its password to blank. So if you have forget Your user account password then try this:
Start system and when you See Windows Welcome screen / Login screen, press ctrl+alt+del keys Twice and it’ll show Classic Login box. Now type “Administrator” (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from “Control Panel -> User Accounts”.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.
Windows XP and further versions also provide another method to recover forgotten Password by using “Reset Disk”. If you created a Password Reset Disk in Past, you can use that disk to reset the password. To know more about It, please visit http://www.resetwindowspassword.com/
