Administrator password can be broken by replacing sam file in system32\config by the sam file in repair folder of windows. it can be easily done on a machine with dual operating systems, simply log on to os other then the one whoes password is to be cracked the way is exactly same as written above but if there is a single os on a machine then there is only one way i.e to use ms dos start up disk or some other boot disk and replace the sam file in config folder with the one in repair folder
note:- this method works only if hard drive is FAT32 formatted because NTFS drive does’nt take boot from Ms DOS
This way you can remove the old administratOr password as if the windows is newly installed and the password was’nt set

BackTrack is a Linux-based penetration testing arsenal that aids security professionals in the ability to perform assessments in a purely native environment dedicated to hacking. Regardless if you’re making BackTrack your primary operating system, booting from a LiveDVD, or using your favorite thumbdrive, BackTrack has been customized down to every package, kernel configuration, script and patch solely for the purpose of the penetration tester.
BackTrack is intended for all audiences from the most savvy security professionals to early newcomers to the information security field. BackTrack promotes a quick and easy way to find and update the largest database of security tool collection to-date.
Our community of users range from skilled penetration testers in the information security field, government entities, information technology, security enthusiasts, and individuals new to the security community. Feedback from all industries and skill levels allows us to truly develop a solution that is tailored towards everyone and far exceeds anything ever developed both commercially and freely available.
Whether you’re hacking wireless, exploiting servers, learning, performing a web application assessment, or social-engineering a client, BackTrack is the one-stop-shop for all of your security needs.
The evolution of BackTrack spans many years of development, penetration tests, and unprecedented help from the security community. BackTrack originally started with earlier versions of live Linux distributions called Whoppix, IWHAX, and Auditor. When BackTrack was developed, it was designed and developed by seasoned security professionals to perform penetration testing from one live CD and not leave remnants of the on the laptop itself. It has since expanded to being the most widely adopted penetration testing framework in existence and is used by the security community all over the world.
What's New in This Release:
Kernel 2.6.35.8 – *Much* improved mac80211 stack.
USB 3.0 support.
New wireless cards supported.
All wireless Injection patches applied, maximum support for wireless attacks.
Even *faster* desktop environment.
Revamped Fluxbox environment for the KDE challenged.

New BackTrack Wiki with better documentation and support.
To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands.
First run the following to get a list of your network interfaces:
airmon-ng
The only one I've got there is labeled ra0. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).
Now, run the following four commands. See the output that I got for them in the screenshot below.
If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully "faked" a new MAC address on your network interface, 00:11:22:33:44:55.
Now it's time to pick your network. Run:
airodump-ng (interface)
To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else. Full size
Like I said, hit Ctrl+C to stop this listing. (I had to do this once or twice to find the network I was looking for.) Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands.
Now we're going to watch what's going on with that network you chose and capture that information to a file. Run:
Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose "yoyo," which is the network's name I'm cracking.
You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command:
aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (essid) (interface)
Here the ESSID is the access point's SSID name, which in my case is yoyo. What you want to get after this command is the reassuring "Association successful" message with that smiley face. Full size
Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with the yoyo network on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the "#Data" column—you want it to go above 10,000. (Pictured below it's only at 854.)
Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though the yoyo AP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many. Full size
Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected:
aircrack-ng -b (bssid) (file name-01.cap)
Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension.
If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this:
The WEP key appears next to "KEY FOUND." Drop the colons and enter it to log onto the network.
Problems Along the Way
With this article I set out to prove that cracking WEP is a relatively "easy" process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key.
So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline. To see the video version of these exact instructions, check out this dude's YouTube video.
