Breaking Windows 2000/2003/XP/Vista Administrator Password

Going by my word posting here about a simple tool which will break Windows 2000/XP/2003’s Administrator account’s password.

Before starting, for newbies…

Windows NT 5.0 = Windows 2000 (all edition)
Windows NT 5.1 = Windows XP (all edition)
Windows NT 5.2 = Windows 2003 (all edition)

So throughout this post I will refer our target as Windows NT 5.x (as following content are equally applicable to all Windows NT 5.x OS family).

So lets start the fun…
You will be surprised to know that you can break into any Windows NT 5.x system without any software tool 80% of the time! For rest you need a software like below!

First lets get to 80% of the vulnerable system….

In Windows NT 5.x, you can create any no. of user with different names, privileges and optionally password.
One such account with highest privilege level, with user name “Administrator” is setup by default.

At the time of installation Windows NT 5.x prompts for password but many systems are setup by vendors and other person. The end-user of this system is different than one who installed it. These lazy people are always in hurry and often left this password as blank.

The irony comes next. In final step of installation you create an account with mostly your first name. Lock it with password(optionally) and start using the system. Now on welcome screen you see account(s) with different name. But have you never see this default “administrator” account unless you boot in “safe mode”.

Now if you can’t see “administrator” account on screen (as with Windows XP login default screen), just pressย  “CTRL+ALT+DEL” and it will change login “screen” to login “box” where you can type “administrator” as user name! This is what works 80% of the time.

Now for rest of the 20% system….
There are literally more than 100’s of tool available on Internet and the tool I use is a small Live-CD named ntpasswd created by pnordahl. I got it from my hacker friend Surun.
Burn this ISO on a CD. Its bootable image of approx 2.7 MB.

It has Linux OS with text-mode only. No Linux Knowledge Require here to use this disk. ๐Ÿ˜‰

After booting from CD. A menu driven program will start with options and their description at each level.
READ EVERYTHING BEFORE GOING AHEAD as one mistake may make the target machine unusable.

One mistake may crash the system to the reinstallation phase! So test it first on systems from college, office, etc! ๐Ÿ˜‰

It worked 100% of the time….
As its 3.03 MB (after extracting) you can burn it on a mini-CD and keep it in your wallet all the time, so can roam around having master key to all systems having Windows NT 5.x family OS!

I tried with DELL D630 Laptop
OS: Windows XP pro

After booting …it shows
“Please select partition by number or
a = show all partiotions, D = Automatically load new disk drivers ….

I have seleted the “a”….
but nothing showing …it showing above options once again…..

finally…i couldnt chage my laptop admin password….

Rahul Bansal April 14, 2008

Did you tried another option – to press D.
The menu comes when the program in disc fails to locate your hard-drive time.
Technically it uses old linux kernel which may not be compatible with new hardwares.
If you have knowledge of hardware/linux, the you may try to load hard-disk driver manually. But DO IT ON YOUR RISK as it may damage the whole system.

Sheraz May 6, 2008

I downloaded the winpass.rar and unpacked it. In it there was another rar file. After unpacking, it revealed somefiles with funny names like ascii characters. I bunred that to CD but it didnt BOOT. Now what.

Rahul Bansal May 6, 2008

In winpass.rar there is a ISO file. It seems ISO files are by default associated with winrar application on your system.
You need to use Nero like software to burn ISO file so as to make bootable CD.
Here you seem to create a Data CD. It won’t work… ๐Ÿ™

Humash September 14, 2008

plz rahul could u send me the link for downloadin the zip file coz i downloaded it but it’s comin with .txt
so wat to do in this case or plz forward me that file to ma email
thankin youuuuuuuu

Rahul Bansal September 18, 2008

@Humash – Just updated this post with new links. Please check again. ๐Ÿ™‚

Aditya September 18, 2008

Does this work on Xp SP3? I wrote a small “OS” in ASM and C++, that did the same, but that stopped working with SP3.I never made that public as I feared script kiddies misusing it.
Hint 1: Basically, there are certain commercial apps available, which infact are even supported by Micro$oft!!
Hint 2: Recovering or resetting the Xp password involves a kernel specific file,which cannot be modified unless you have full Ring0 mode(protected mode).
These two hints and google will help anyone who wants to break XP password for any user.But yea, with SP3 there are certain changes, which I have not looked into.

Rahul Bansal September 25, 2008

It work on Vista as well and it is continuously updated so try it… ๐Ÿ™‚

engieer asif November 18, 2008

sir i m student of engineering can u tell me when we r starting windows xp nd there is some administrator passwrd there how i can break it can u any suggestion please i m waiting ur raply sir

Anirudh December 17, 2008

The above method is neat, its a little “compressed-password-breaking Linux” kinda. The elite way of doing that could be using BackTrack , Backtrack is special version of Slackware Linux, custom built for security purposes.
A Black hat can use Backtrack to compromise the windows security all the way ๐Ÿ˜‰
give it a shot !

Rahul Bansal December 20, 2008

I will check it for sure buddy. Thanks. ๐Ÿ™‚
I heard about it a lot but never got enough time to try it. ๐Ÿ™

BTW, there is another good solution
I have purchased Windows Password Recovery Tool .
it not only supports XP, 2000, and NT, I have personally tested it with Vista Home Premium and Ultimate. It works perfectly to reset any local user account to a blank password. I Wrote it to an old 128mb USB flash drive do this. Booting up and clearing a password takes a minute or two works like a charm.

Ahsan February 4, 2010

My problem is a little different from the ones that are mentioned here so far. Let me Explain:
I am using Windows 7 (32 bit) and have installed the Windows Virtual Machine. Inside that virtual machine, I have installed XP. I have another virtual disk(.vhd file) that contains Windows Server 2003, is sitting on the C: drive of Windows 7. I have created a connection to this Virtual Disk from the Virtual Machine that I have mentioned before. So now, when I open the Windows Virtual Machine, I see two icons – one for the XP and one for the Windows Server 2003. When I try to open and login to the Windows 2003 Server, it asks for an Administrator’s password which I forgot. I did not set up any other user for this environment. Now, any ideas from anybody about how do I sove this problem?

To put it bluntly, I need to break in to this system but haven’t have any luck yet. Any help with this will be greatly appriciated.

Windows Password Key

Saved me today. After many hours of installing and tweaking a brand new PC, something went wrong. I was not able to log into the only Administrator account I had, once the machine had been rebooted.

I burned Windows Password Key to usb, followed the onscreen prompts and in a few minutes was back in the machine.

What a lifesaver!

It will become a permanent part of my toolset for fixing Winndows password problems.

Cally August 31, 2011

A few days ago, I lost my windows vista administrator password. I solved my problem with the help of windows password seeker. Not only support Windows Vista, but also compatible with Windows 7, I tested it on my laptop installed with Windows 7 and remove the local user and admin accounts password successfully. Itโ€™s worth trying. You can download it from:

Vivek Shah April 19, 2012

Thanks a ton, i was one of those 80% who was breaking my head since a week and got the solution in a second. for those who are visitors here, at the login screen i pressed control+alt+del and gave the username as ADMINISTRATOR and enter, and voila i was able to login and change my password.
